Hello and welcome. I'm Teresa Eyring, the executive director and CEO of TCG, and I use she, her, hers pronouns. On behalf of the board and staff of TCG, I want to say thank you for joining us at Convergence, the first half of our 2020 TCG virtual conference, Re-Emergence. Before we get started, we'll take a moment to offer our respects to the many lands on which we gather, and to honor the traditional stores of these lands. If you have a land acknowledgement as part of your personal or organizational practice, we invite you to share them in the comments now. You'll see now a map of native lands on your screen. Like many of you, we've made a practice of land acknowledgement at all our gatherings. We do this to offer recognition and respect, to broaden awareness of the history of this land, and to begin to repair relationships with native communities. And it's important that this responsibility not always fall on native people. As we move to a virtual gathering, we do so knowing that many native peoples do not have access to these technologies, and that these online tools contribute to the climate crisis that disproportionately impacts indigenous communities. In your own time, I invite you to review the land acknowledgments in the comments, and consider how we might act in solidarity with our native colleagues who are experiencing the worst of this pandemic. To help get us started, I'm joined by my friend and colleague, Adrian Budu. Thanks, Teresa. I'm Adrian Budu. I'm the Deputy Director and COO of TCG, and I use he, him, his pronouns for pronouns. Our coming together today is bittersweet, because our big production, the National Conference, was supposed to be in rehearsals right now, soon to open in beautiful Phoenix in June. But like so many of you, the pandemic has made us pivot online, which for many theater people will never be the same as a live event. But just because they're not at the same doesn't mean they can't be deeply meaningful, as we trust our time together will be. But first, we need to take a moment to honor Phoenix. We were just so excited to bring the theater field to Phoenix. We couldn't wait to share the thriving art scene, wonder at the natural splendor, and honor the native communities upon whose land we were together. Above all, we couldn't wait for you to meet their amazing theater community. They are a generous, kind, committed, and visionary group of people. And we hope that when the pandemic fades, you'll find time to visit them. We'll have a chance to hear from our host committee chairs later in this session. Before we get started, we also want to wish Ramadan Mubarak to all of our Muslim friends and colleagues who are observing Ramadan now. We know our Muslim friends are not only feeling the loss of connection into theater, but also missing the deep connection that comes from prayer shared in person. And we're sending all our love to you. One small way that we can support our Muslim colleagues who are fasting is to refrain from drinking or eating meals and camera during our Zoom meetings. We'll be in touch on that later too. Thank you, Adrienne. Now, the name of this two-part conference is Reemergence, and that title holds multiple meanings. One of the things it means is that our conversations are intended to be emergent, to live in an open, generative space. For while this pandemic is many things, a crisis, a tragedy, and an existential challenge for our field, it is also surely a transition, a portal through which our field must pass and be changed. If we move through this transition with care and intention, we hope that we can come through these losses stronger than before, so convergence is intended to be a space of collective envisioning. That said, we know that many of you join these conversations needing immediate tools and resources to keep your theaters and theater careers alive. TCG is committed to providing these tools and resources as well. Moving between a visionary space while also navigating complex federal legislation and budgeting scenarios isn't easy, but for theater makers, it's also not unfamiliar. And for us at TCG, we believe that a holistic approach, one that responds to our immediate needs while strategizing about our future, is essential. That's why TCG has assembled a five-part responsiveness framework. TCG's response efforts will, one, stabilize the field by advocating for and disseminating information about relief funds. Two, organize theaters through virtual gatherings and online resource sharing. Three, communicate the existential need of theaters now and the intrinsic role theaters will play in stage in our country's recovery. Four, innovate new ways of connecting with audiences and creating our art form. And five, transform the systemic challenges our field faces to emerge stronger from the crisis. A core part of our stabilized efforts is our advocacy at the federal level. TCG works in coalition with other arts advocates to ensure that not-for-profit theaters and theater artists are included in critical relief legislation. You've also supported that work through the 7,000 messages you've sent since the pandemic to your congressional representatives. This work is led by Lori Baskin at TCG and she tells us we can't let up. Keep those messages coming to Congress. We organize through affinity-based online communities in the TCG Circle where theater people have sent over 3,000 messages to each other since the pandemic. We've also been working with journalists to ensure that the needs of the field are clearly communicated with articles posted in the New York Times, NPR, New York Magazine, Forbes and many others. And we've begun to lift up the innovative ways theaters are connecting with audiences. Most recently in our webinar, virtual toasts, online galas and donor engagement. That brings us to our work today, the work of transformation. Convergence will support the urgent need of connection and collective action as we grapple with the changing needs and challenges facing the nonprofit theater field. We will do what the TCG conference has always done best, bring different types of theater people together for emergent conversations and ideation. The wonderful Priya Parker in her book, The Art of Gathering talks about how to articulate the outcome you hope for from a gathering of people. She says, think of what you want to be different because you gathered and worked backward. On the other side of convergence, after you've logged off your last Zoom call of the week and move into your weekend mulling over what you've talked about and experienced, we hope that you feel different about the work ahead than you did coming in. We hope you're both challenged and comforted by these conversations. We hope that some offer you with tools and ideas, but we also hope that some bring you into the community with theater people you might not have met otherwise. We hope that in those communities we begin to reckon with what this time is teaching us as a field and how we might acknowledge our losses together and imagine and forge a new path forward. And we theater people know we have a long history of adapting and thriving in the face of plagues, pandemics, terrorism, global conflict and economic disaster. We have the opportunity to work through this crisis with an eye toward transformation, toward leaving behind the practices that weren't working and maybe never worked to rebuild our theaters and our communities with a focus on justice, equity and inclusion. Let's do that in the coming days. I want to express huge admiration and love for TCG's conferences and field-wide learning team and hand it over to its fearless leader, Devin Berkshire. Thanks, Adrienne and Teresa, for setting us up so nicely. Hi everyone, I'm Devin Berkshire, my pronouns are she or hers, and I'm the director of conferences and field-wide learning here at TCG. I'm also the mother of Nina and Diego, and I want to echo the gratitude to all of you for joining us here at our first virtual conference. This has been quite the journey for TCG and one we didn't think that we would be taking this quickly. So we really appreciate the patience Teresa was referring to as we know it's been a lot to keep up with on your end. So thank you for bearing with us as we all learn together. The staff on this end is pulling off some really miraculous work, so my gratitude also extends to them. Our hope at the moment is to take a little time now to do what we would do in a live conference and our How We Show Up session, which we've been doing at the top of every TCG conference since 2015. How We Show Up is in many ways about getting us all on the same page for the work ahead for the three days we'll be together. The first How We Show Up, which was conceived by my wonderful colleague, Karina Shulenberg, and led by my amazing predecessor, Dayfina McMillan, I offered up the invitation to attendees to join us in all the fullness of their humanity. Not just as colleagues in the field, but as people who are sharing space while embodying all their areas of identity. So we've continued to offer that invitation at every How We Show Up since then, and it's a lot to ask of you at this time to join us in all of your humanity and vulnerability. And it's an even taller order when we're trying to do it all from our own homes through computer tablets, computer screens and tablets, without being near each other and without being in the same room together. For a field that's meant to gather people in person, this is a difficult task, and we acknowledge that and will continue to express our gratitude to you for your time and energy. To make it a bit easier, we'd like to introduce overall meeting agreements for our time together. Your facilitators in your different sessions may reintroduce these in those spaces. They may build off them, they may invoke them just as we're offering them now, or they may create new ones with you. But these are all some of our favorite guidelines for sharing space, some of which may be familiar to you. These agreements come from TCG, from organizations like AWARDA, and from different facilitator networks that we interact with. So let's take a second to talk through these. Make space, take space. This refers to being conscious if you're someone who tends to speak a lot, make sure you're allowing space for others to participate. And if you're someone who tends to pull back, try to step out of your comfort zone and lean into participating more. No one knows everything, everyone knows something, together we know a lot. This refers to a kind of collective intelligence we should be allowing to emerge from these gatherings and acknowledges that the knowledge we share is greater than the knowledge held by any one of us. Allow everyone to speak for themselves, not on behalf of a group. Let's commit to speaking in eye statements in these conversations. Agree to disagree, but please do not disengage. This refers to the welcoming of healthy conflict, as we know these conversations may get challenging, but please don't let heated moments of exchange cause you to disengage from them. What's learned here leaves here, what's said here stays here. This is TCG's version of confidentiality. Didn't come from us, but while the conversations in many of these spaces will be recorded, except for the personal identity groups, TCG will not distribute these recordings, they'll only be used internally for archival purposes. Respect the agenda, but hold it lightly. We want to encourage trusting your facilitators to have crafted the agenda for your time together well, but they are also prepared to be agile if necessary and if the energy of the group is pointing in a different direction. Be a person, look for moments of joy. We'll say this a lot, and I want to credit the wonderful Stephanie Ibarra for first putting it this way to us, the be a person part, but in this kind of space, that's particularly important. We're all home, we have pets and kids and noise and it's all okay, but please do stick with us enough to discover joy together, whether you experience the joy with your kids sitting on your lap or in a rare moment of privacy. Now to talk more about our suggested rules of engagement on our digital platforms, two members of the phenomenal TCG conference team, and Charlone and Sam Morialli. I'm going to pass it to Sam and Anne to tell us now a little bit more about how we're asking you to interact and zoom with us during convergence. Hi everybody, I'm Sam Morialli, I use they and he pronouns and I am the TCG conference coordinator for the 2020 virtual conference. And I'm Anne Charlone my pronouns are she or they and I'm the TCG conference manager. Sam and I would love to spend a minute offering a kind of virtual vocabulary for our time together. Almost all our sessions will be happening via zoom platform that I'm sure you've all gotten to know very well over the last several weeks. For how to show up in your zoom rooms and a lot of this information can be found in our welcome posts on mighty networks easily accessed in the discovery section, along with screenshots of how to find some of this functionality. So, first, set your name and TCG we are encouraging you to set your pronouns as well. So as you can see even in this recording here they're Samuel Morialli with my pronouns and parentheses and stay on mute except for when it's your turn to speak. Please use your camera to the extent that you're comfortable just so people can see you at least physically reacting your attention there. Please use the raise hand function on zoom to signal when you would like to speak. Feel free to use the chat box to participate if you don't want to speak but minimize crosstalk in the chat. And the chat can be used in a couple different ways. You can use it to ask questions of your facilitators and you can do that by noting that with question marks or you can support a speaker or thoughts notated like so. Be a person, little ones and pets are welcome on camera and we recognize the extraordinary caregiving responsibility being placed on some folks during this time. Please respect our colleagues who are celebrating Ramadan by turning off your camera to eat or drink. And use the clock away function to signal your absence from your computer especially during breakout periods. A lot of these zoom tips with screenshots can be found in the welcome post on the Convergence Mighty Network that we'll talk more about in a minute. And please let us know if you have questions during Convergence about zoom or anything else by emailing us at redashemergence2020atTCG.org or by direct messaging the mighty network member named TCG support line and someone at TCG will get back to you right away. We just want to ask you to offer grace and generosity to your facilitators and staff hosts on Zoom calls who will also try to help you work through any technology issues that you may have. And we will have them and it will be okay. Now I'll pass it over to our intern Amelia, the most vital member of our team. Amelia, can you tell us a little bit more about Mighty Networks? Thank you, Sam. Yes, I can. Hi, everyone. My name is Amelia Smart-Denson. My pronouns are she, her, hers, and I'm the conferences and field-wide learning intern at TCG this season and what a season it has been. I have also set up a lot of the Mighty Network platform that houses most of the Convergence programming info. And rather than spend a lot of time now telling you about it, I would encourage you to go to this post in the featured posts section of your home page, as well as the discovery section of the network and read a quick how-to of how to make the most of your use of the new platform. It's really user-friendly, but email us at the email that Ann mentioned if you have any trouble. Back to you, Devin. Thanks, team. And what an amazing team you are, for real. Okay, everyone, we are looking forward to seeing a lot of you over the next couple of days and we're here for any support that you may need. So with that, I'd love to pass this to my wonderful colleague, Elena Chang. Thank you, conferences team. My name is Elena, and my pronouns are she, her, hers, and I'm the director of ED&I initiatives at TCG. One of the things I've noticed is how my sense of time has changed during this pandemic. It's harder to feel which day it is and sometimes it feels like we're moving both really slowly and way too quickly at the same time. One of the things that helps me is taking this time to say thank you. And so I want to say thanks to our amazing conferences team who have rallied this convergence together. I also want to take a moment to really lift the wonderful work behind the scenes of our new marketing director and goddess of all online things, Erica Lauren Ortiz, for her tremendous support this week. Finally, I also want to lift up how draining these video meetings can be. And so if you want to stretch, move your body in any way that feels good, please do so. We look forward to connecting with you more directly throughout the week, but team ED&I here thought we'd provide a bit of context on this year's identity affinity spaces. Amidst COVID-19, it's time, more than ever, to lean into specifically anti-racist, anti-homophobic, anti-sexist, anti-Abelist practice. And what many individuals from the POC, LGBTQ disability networks have been sharing with us has been more than sobering. At TCG, we continue to interrogate this. The fact is, things have not been inclusive for decades before this pandemic. It's not a question of what can be done. It's more of an urgent question of what needs to be done. And it's with that thinking that we've engaged with many networks of color, LGBTQ initiatives, and leaders from the disability theater networks to center by foreign about conversations as part of TCG's convergence. Hi, I'm Sierra and I use she, her pronouns. I'm the equity diversity and inclusion intern at TCG. As part of our convergence programming, we will have a specific identity affinity session for people of color. This session will gather all who identify as people of color into one session before breaking out into specific racial identities for discussion. They'll then reconvene at the end of the session to share out what each group talked about. There will also be a session for white people around anti-racism and how to do the work. This space is specifically for and facilitated by white people because we should not expect that kind of labor and teaching about anti-racism to come from people of color. It's important to have a space where white people can take the responsibility of doing and learning about the work themselves. In terms of breakout sessions for people of color, there are five race specific sessions. The native session will foster a discussion of native community needs, how the native community can support one another at this time, and ways for that community to move forward and heal. The MENA, or Middle Eastern North African Session, will introduce the newly formed MENA Theater Makers Alliance, its purpose and mission. The session will then invite feedback and discussion around ways to build a stronger MENA network and the best way to advocate for MENA artists. The Latinx Session will focus on uplifting bright spots on the horizon and noting the most beneficial actions across the field that have happened in response to the pandemic. This session seeks to imagine how the Latinx community and Latinx Theater as a whole can continue to move forward from this moment. The API, or Asian Pacific Islander Session, will be a collective reflection during these troubled times and a chance to discuss messaging as a community, specifically as it regards to the anti-Asian racism and xenophobic attacks currently occurring. The Black slash African American Session will center on community care, specifically by looking at the current needs of the community, how to care for one another and what that means and looks like during times of crisis. Thank you, Sarah. Hello, my name is Sarah Machiko Haber and I am she or her pronouns. I am the Equity, Diversity and Inclusion Initiatives Associate at TCG. We have three more Personal Identity Affinity Sessions this year that I'd like to share a little about. First, those who identify as having a mixed identity are welcome to attend in the mix, the mixed identity and multi-identity affinity space. This session, facilitated by Kayla Kim-Vodipeck and Kanisha Foster, is for anyone who identifies as mixed race, mixed identity, multi-identity individuals who are part of a multi-identity family, for example, adoption, interracial marriage, second generation, and allies. I'd like to live that mixedness is not limited to racial identity. The second space is the changes that remain in affinity space for theater and disability, facilitated by Reagan-Linton and Claudia Alec. This affinity group is for theater artists with disabilities, allies, and the theaters that support them. We've heard frustration from many people that the conversation around disability in theater frequently focuses on audience accessibility and often excludes artists with disabilities and their art. Claudia and Reagan have crafted a session that will discuss unique challenges and big picture questions, like how will we center the leadership, resilience, and expertise of disabled artists during this moment and beyond. The final affinity space that we'd like to let you know about is imagining an intersectional and intergenerational LGBTQ theater community, facilitated by the new coordinator of the National Queer Theater Festival, Brie Inge Schwartz. This is a buy for and about session, so if you identify as a member of the LGBTQ plus community, please join the conversation. Brie has created a really dynamic session that has time for both group conversation and one-on-one connection. There's going to be space to discuss who is usually featured and who is often left out of the LGBTQ theater narrative, space to identify needs, space to support each other, space to hear folks who have been doing the work for many years, and space to share about current projects. We hope that you will join us for the personal identity sessions that you identify with, and we're excited for the conversations that will happen. Last but not least, many of you know that ED&I has been utilized almost as a catch-all to increase awareness around depression, like the ongoing critique of how systems can focus on the optics of inclusion versus activating values in conjunction with community. We look forward to the new emergent conversations that arise out of not only this week's identity affinity sessions, but especially to continued exploration of the ways that power, access to resources, cultural oppressions show up in every single session. Sessions that we too are privileged to participate in. Now let's hear from our wonderful Phoenix committee co-chairs, Cristina and Steve. Chísimas gracias Elena. My name is Cristina Marine, and I'm the program director for theater and film at Phoenix College here in Phoenix, Arizona. My pronouns are she, her and hers, and I want to pass it to my wonderful co-chair for the local host committee, Steve. Hi, I'm Steve Martin. My pronouns are he, him, his. I'm the managing director at Child's Play, and it gives me great pleasure to welcome you to convergence. We are so sad that we're not all together here in Phoenix right now, although you might be less sad since it's 105 degrees. But we were really looking forward to sharing the conference with you next month. But we are very happy that TCG is prioritizing the health and safety of all of its constituents. We wanted to experience, to help, to let you experience all of the great and wonderful arts and cultural amenities that we have. Artists, organizations, installations that we have here in Phoenix and in Arizona were disappointed that you can't be here. It would have been a great time to experience what a real dry heat is all about. The conference was also going to coincide with First Friday, which was something that we were very excited to share the arts community with you here in Phoenix. We also have a great Indigenous community from the Navajo Nation down to the Pima and Gila Indian Nations. We are also, I understand, going to have Native Nations here, which I'm hoping that all of you will get to experience sometime in the future. We also have a lot of theater in Spanish and Latinx culture and heritage is here and vibrant and alive. And so we wanted to share that with you as well. TCG has played a very, very important role in my life. I was a very young theater manager. I didn't know a lot. And then I started coming to the TCG conferences and I started meeting my peers and I started hearing new ideas and sharing experiences. And it changed me and it helped me to become a better manager, a lifelong learner. And it helped me to create what I believe is a more inclusive and equitable organization. So thank you TCG for that. I think that we were really looking forward to is having a lot of our students from the many community colleges and state schools here in Arizona participate in volunteering and really experiencing the essence of TCG. We want to thank everybody at TCG for thinking of Phoenix and our unique cultural experiences. And for wanting to share what we all know about with the rest of the theater community. We also really want to thank every single person who was part of our local host committee.  So a shout out to all of our amazing, amazing comrades here in Phoenix. On behalf of the entire host committee, we want to say thank you. And now we'd like to pass it on to everybody's longtime TCG friend, Emilia Cachapero. Hi, I'm Emilia Cachapero. I'm the director of artistic and international programs at TCG. And here at TCG, we have a history of professional development programs like our rising leaders of color and our Fox Foundation resident actor fellowship program. And we often like to start our working sessions with some grounding work. And we thought that it might be a good idea to do that with you all. Now, first off, it would be great if you have a piece of paper handy a loose sheet would be perfect. And then a pen or pencil nearby, we're going to be using it later. So just taking a breath here. We're all dealing with a lot right now. And it isn't the load that weighs us down, but it's how we carry it. You might have read the article in last month's Harvard Business Review that was titled that discomfort you're feeling is grief. And it talked about grief in a variety of ways, the loss of a loved one, the changing world and anticipatory grief. It's that feeling that we have in an uncertain world. But if we can name it, we can manage it. There are many ways to do that. And I invite you to work with me on some conscious breathwork. We all breathe, at least I hope you are, but we don't always think about how we breathe. So sit in your chair.  And if it's difficult for you to keep your eyes closed, you might want to just lower your gaze to the tip of your nose. That works just as fine.  So on a scale of one to five with one being the lowest and five being the highest, where are you on that continuum?  So one being very, very calm, five being extremely stressed out. Where are you? And I'd like you to then scan your happiness level, one being very, very unhappy and one joyous.   A lot of studies have shown the value of silence.  And breathing is meditation for people who say they can't meditate. So we're going to focus on a three part breath.  And with your inhale, think about pushing your hands away with your belly on the exhale, your hands come closer in. And again, inhaling, pressing your hands away, exhaling your hands come closer in and moving your hands to the sides of your ribs. Similarly, when you inhale, you're pressing your hands away. And on the exhale, your hands come closer to the center and moving your hands to your thoracic area. It's that heart and chest area and lightly rest your hands on the thoracic area. And as you inhale, think of your hands rising and on the exhale, your hands lower and take that a couple of times at your own rate. You may be breathing slower, you may be breathing faster than me. And in a moment, we're going to do control breath work. It's going to be a four, seven, eight breath. So you will be inhaling on a four count, holding for a seven count and exhaling on an eight count. A lot of people may find some discomfort when you're holding your breath for a long time or longer than you're used to. And sometimes it can feel claustrophobic. So not necessary that you hold it for the entire seven, but maybe six or five, as long as it's longer than your inhale. So we'll try that. So an inhale on four count and your four count. And when you're ready holding it for seven, exhaling eight and repeat that a couple of times, four, seven, eight. Inhale four, hold seven or six or five and exhale eight. Now, as you're doing the four, seven, eight breath, the more oxygen that comes into your lungs, it makes your lungs even stronger. And that's incredibly important now, particularly with our health concerns. So continue on. There was a British study with asthmatic children. And with these kids, they had them enroll in wind instrument classes. And so after a few weeks of those classes, it was found that the nighttime symptoms were reduced by 78% for these kids. And the daytime symptoms were reduced by 53%. And it was just by work on breath and strengthening the lungs. Continue on the four, seven, eight breath. And just put your attention to the frontal lobe of your brain. It's a bit like the recipe box that my mom had when I was a kid that many of you might have had the same thing where she had an index box that was crammed to the gills with recipes that she had written down and things she had cut out from packages. Well, our frontal lobe is like that area. It's got an overuse and an over storage of information.  It's that point between your two eyebrows and gently make a few circles in one direction, make a few circles in the other direction. And again, at your own time, do that a couple of times. And when you're ready, you can flutter your eyes open and look for your piece of paper and your pen or pencil.  And what I'd like you to do is think about three promises that you're going to keep between now and the weekend. So one promise is to yourself. One promise is to your theater circle. And one promise is to your community. And to yourself that could be anything from you're going to do some conscious breath work in the morning or you're going to have a cup of tea instead of coffee, or you're going to take a long walk at the end of your day. A promise to your theater circle could be you're going to check in on somebody who you haven't talked to in a while. Or it could be you're going to share a photo of you and some of your theater circle folks from before this pre-COVID time. And with your community, that's self-defined. So however you define your community, what you might do to help your community. It may be raising your windows at seven o'clock every day and feeling the community of folks on your block as you're cheering frontliners. It could be anything else. So write those down on your paper, give you a moment here. So I'd like you to keep the paper near you someplace where you can reference it, where you can be reminded of the promises that you're going to keep or work on keeping over the course of this week. Thanks a lot for spending time. And I hope to see you over the course of the week. Thank you, Amelia, for leading us with such gentleness and grace through the grief that so many of us are feeling. I'd ask us all to take that gentleness and grace with us as we move through the next three days together. This is TCG's first fully virtual convening, and we may make mistakes along the way. Each of us may find our stress response or grief show up in these meetings in ways that surprise us. When these mistakes and moments of vulnerability happen, let's practice that grace and gentleness with each other. If we do, we'll surely find moments of deep connection at a time we need it most. With that, thank you again from all of us at TCG, and we look forward to this precious time together with you all. So as we begin convergence, I would like to take a moment to give acknowledgement to those who empowered us to bring this week's programming to the field. My name is Kevin Biderman, and I'm the Director of Institutional Advancement of Partnerships with TCG. And over the last few weeks, TCG has been in frequent conversation with the following funders and sponsors, all of whom are committed to the stabilization and recovery of our field. This week's programming in the digital space would not have been made possible without their support. Now, normally in the theater, I'd ask for you to hold your applause, but now that we're in the virtual space, I'm welcoming your cheers and applause as you are able. So please join me in thanking the Doris Duke Charitable Foundation, the Andrew W. Mellon Foundation, the Howard Gilman Foundation, Hearst Foundation, the National Endowment for the Arts, the Ruth Easton Fund of the Edelstein Family Foundation, TRG Arts, the Sherri and Les Biller Family Foundation, Fisher Decks Theater Planning and Design, Audience View, Walt Disney Imagineering, Capacity Interactive, Management Consult for the Arts, Agile Lens Immersive Design, the Richenthal Foundation, Blue Print Advancement, the New York Council on the Arts, the Arts and Culture Department from the City of Phoenix, the Arizona Commission on the Arts, the Institute Financial Wellness for the Arts, and Next Stage Design. Thank you for supporting the first TCG virtual conference. And now, I'd like to welcome my colleague, Erica Lauren Ortiz, to the screen. Thank you, Kevin. I'm TCG's Director of Marketing, and this is not only my first conference as a member of the TCG team, but this is also the first time that TCG is bringing the National Conference to the field with no registration fees. And as you know very well, even no cost programming requires quite a few costs to pull off. In lieu of registration fees, I hope that you'll consider making a donation to TCG. Your gift not only helps us to serve the field with programming just like this, but it ensures that access to these resources remains open, particularly now when we need it the most. So, if you're able, please join me in supporting TCG and visit this link to learn more. Last, the curtain will rise again because theater is vital. If you're able, please consider supporting this work and enjoy Convergence.


Quarky opens up a world of opportunities for us to tinker on AI, machine learning and Internet of Things. With Quarky, you can explore the artificial intelligence, program robots, game, steam project, perform fan activity and much more. It's a simple piece of hardware with an enormous amount of depth. It makes it easy to teach kids the complexities of computers and robotics and coding, but it does it in such a simple way. And what I love is that it's easy for teachers or facilitators or for a parent to learn how to use it fairly quickly and easily. The Quarky uses Pigtail Blocks for programming. It's easy for students and teachers to find coding issues. It's so useful for AI education. Quarky is an amazing educational pocket-sized PC. It comes with a multitude of functions and its size is hard to beat. I tested this nice robot which called Quarky and I believe it's fantastic and it will be a great companion to the kids. They can learn a lot from it, especially about coding, robotics and artificial intelligence. This is the best kit for an artificial intelligence-based learning and you should try it with your kids in your classroom.


Hey guys in this video I'll be giving you a review on Corpads on a Deathadder Viridus. Now these Corpads cost around $10 shipped. That's pretty expensive for just some layers of PTFE but they do come in two sets which is good. So before the glide wasn't too slow or too fast on my stock mouse fee which are also PTFE. After I switched it felt about the same. It felt like it was a little bit faster when I made small movements. It was easier to control when I made micro adjustments in Valorant. The most important thing however is that the glide is more consistent. I think this could be attributed to the fact that these feet are more than twice the depth of the stock razor mice fee. It also felt way smoother like I was gliding on a cloud. Now on my Viber mini the glide still feels nice especially for stock mice fee. But I feel like razor kinda cheap down under PTFE material. The Corpads are 100% PTFE so that's probably why the glide felt more consistent and smooth. Longer time I could feel the texture on my mouse pad with the stock feet. I think it's because it's thinner or because I was pushing too hard. Either way the Corpads fixed it. Another thing is that they gave you more surface area on the feet. The razor's stock feet didn't come around the mouse sensor. I think on other models like the Logitech GPrail it was a huge upgrade because the default feet didn't come close to the surface area of the customized feet. Plus if the default feet wear down you can't really replace them. Here you have two sets of replacements and they would generally last longer than the default mice fee anyways because of the depth of it. So do I think it's worth it? Yes it's more consistent, more comfortable, lasts longer, has more surface area and you get another set if they wear out. For 10 bucks that's a huge upgrade in my opinion. I got these from Lethal Gaming Gear but you can also find them on eBay in other sources. Thanks for watching.


And then are you gonna basically in the sessions talk about the authors that always forget to cite their software so Okay, I'm a little late getting here this morning day two And my dreams my prayers have been answered There's still coffee All right time to go learn about stellar flares So in the UV pass plan is about 1.8 x 1031 birds So one of the strongest players Observed in that theory, but as you can see the in the finals of highlight the energies of the players of the young endorse are Much much greater than those of the all of it works roughly two to three orders of 92 A few decades ago It was a surprise to find that active and dwarfs have bright quiescent non-thermal radio Sorry to show you today new x-ray and Stars from the two open clusters precepting and high Partly to be going around 650 million years old I'm here to ask for start real forgiveness Yeah, you're in trouble. I failed start oilist. I failed I failed to bring failed to deliver a box Oh, I heard about this box.  At least we have somebody who like who actually is responsible Delivered this box that I forgot for the start to oilist booth. Oh I can't wait for got it on the kitchen counter this morning So it's a fitting thing my wife should deliver this today because today I'm thinking about careers Family choices jobs a big part of the double-ass meeting isn't just showing off science isn't just meeting with your collaborators It's about networking. It's about hustling showing off your work Meeting with potential employers trying to get that next job It can be stressful. It's a big networking fair basically So I've certainly made my own specific choices about my career. Of course this week I am balancing family balancing living here and attending a meeting But I've also made choices about which jobs I'm applying for which cities I'm willing to live in And what I'm not willing to do If you don't remove your poster at the end of the day, they will remove it for you. I'm Alex teach. I'm a grad student at Columbia University And I look for excellence Hi, I am Gus Minch. I'm one of the data editors for the AS journals So you were in season one of the double-ass walks. I was in season one yesterday was all about software citations And then today and tomorrow all about data citation And then are you gonna basically in the sessions talk about the authors that always forget to cite the software? so It just got out of an interesting discussion session that was about SETI That's the search for extraterrestrial intelligence basically aliens in the 2020 Decadal survey So this is a survey that's done every ten years To kind of assess what the state of the field is. What are the priorities? What are the funding priorities of the field? SETI has kind of a complicated history in astronomy as it was essentially outlawed and Kicked out from the available funding sources. So NASA NSF. They didn't want to fund SETI research for a long time Now there seems to be openness interest in funding SETI There's a small but growing group of people who are interested in the academic pursuit So I'm certainly one of these people who are interested in seeing SETI pushed forward and pursued and thus funded So it's great to be in the room where a lot of these decisions are happening and to get my tiny bit of my voice heard Being involved in these sorts of like bigger picture state-of-the-field discussions Can be a very influential thing if you can say that not only am I a voice of great science and great ideas But I'm a contributing player in what the decisions are being made. It was interesting. I feel like that's new That's really cool like not just bringing in people but actually trying to make the connection between jobs and scientists I love it The University of Washington And I'm here at this conference just trying to pick up as much bad chocolate as I can It was Russell Van Lynch. I'm from San Diego. I go to UC San Diego, and I study ground works in their magnetic fields My name is Dino, Dino Bekteshevich. I am at University of Washington, Seattle And I work on getting the LSSD software to run in clouds. Okay, it's almost six o'clock For dinner tonight. I'm meeting up a bunch of people from my grad school class So these were the eight of us who entered grad school together and now have taken a ton of different career paths So it's good to catch up and see where life is taking us. We entered grad school ten years ago So it'll be a nice reunion, and it causes one to really reflect on where they're going I don't know what my next job is I think it's it today. See you tomorrow for day three


Hello and welcome to frightfully forgotten brews and today we are featuring lords of death hopped rice lager It is inspired of course from the movie big trouble in middle china It's the name of the the gang that abducts meow yin from the airport lords of death. They know your name That's not good it's kind of a take on a Traditional like american lager, but a bit more hoppy and it's kind of got a east meets west flavor So yeah, I used american pilsner malt And then flaked rice to give it that kind of east meets west vibe and then used hops that kind of like sounded kind of asian ish or like mystical So the recipe is nine pounds of pilsner one pound of flaked rice Five ounces of sriracha ace hops at the boil Five ounces of sriracha ace at the last 15 minutes And five ounces of pacific jade at the last 10 minutes And five ounces of pacific jade at turnoff nice and then use the s-23 Lager yeast which nice and clean yep workhorse of the lager world. It's not as hoppy as I'd hope but it's still pretty clean and You can get that lemony kind of citrusy from the sriracha ace and a little bit of that spicy bite from the Yeah, it's easy going. It's very sessionable. So yeah, you can drink this all night as you you know You don't want to be too He's going to go abduct women from the airport It's a nice buzz going Exactly just enough so you can do it, but not or not not too much so you can't yeah You're gonna be able to pull weapons out of nowhere Where'd you get that? Until next time keep drinking. Yeah


No panicking. So here we start and first question is for more are in single. No, you are you should be Start First question is on your screen and take your time and solve do not jump on do not jump on Solving or let's say, you know quickly finishing it. Take your time. Take your time Even if it takes a lot of time. No worries Okay, so take your time and solve Metaculously with pen and paper, right?  I'm saying all of you have to focus on hundred percent accuracy I don't care about speed if you get on the first position Well, I'm good. No problem. But then if you are not getting it consistently there, that's a problem. So take your time and Solve and all all of you must solve and post your answer I will explain each question. So don't worry about the explanation part so Just and let's say someone is not able to understand In the interest of time, I would request the video will be there. Yes, 100 question 100 seconds The video is there After the session just take the video and look at the solution once again, okay? So for the interest of time, I will explain once definitely, okay? So here is the end and Yeah, so first Answer is okay. So a lot of lot of you have got the right answer. Many of you have not got the right answer. So Okay, never mind. So let me explain this and then we'll go to the leaderboard So it was very simple question the underlying concept was Complementary angles, isn't it? So complementary angles we have studied and that is what you have to you have to apply here So complimentary angle has to be Try now if you can join nothing like it try it. There's no restriction on anyone joining But if you are late, then it is a problem anyways So if theta and 2 theta minus 45 are acute angles such that sin theta is cos So convert sin into cos and compare the functions Compare the arguments you are done. What is sin theta guys sin theta is cos of cos of 90 minus theta Is it cos of 90 minus theta is sin theta? Okay, and this is equal to cos of 2 theta minus 45 degrees and that is what you needed to do Now you can equate the angle. So 90 minus theta is equal to 2 theta minus 45 degrees. So that is 3 theta is 135 degrees This implies theta is 45 degrees and you all know that tan 45 is 1 so This was the answer, right? This is the explanation to the first question and So you can just do q plus q2 whichever the underlying concept is the same. What is the underlying concept? All of you are using complementary angles so Complementary Complementary ratios of complementary angles is it and the basics basics were That sign of theta is equal to cos of 90 minus theta and vice versa tan theta was caught off 90 minus theta and vice versa and Second theta is cosecant 90 minus theta and vice versa Remember this Okay, this one, okay now Okay, understood any problem if any problem put an x otherwise, we will move ahead. Okay. So here is the first leaderboard Of the question so Dax from CHK very good. Keep it up. So let's go to the next problem guys. Okay. So here is the next Problem very simple once again, stay calm. Don't rush through Answers could be deceptive the options could be deceptive. So hence Just relax and Take your time. There's no hurry No, hurry. No hurry. What is that? Is 1 equals to a and b equals to 2 Hi, yes 1 a 1 2 3 4 is ABCD. Thanks for pointing 1 2 3 4 is ABCD. Take your time So this is again based on the same similar concept All of you should be very easily able to do it. Yeah Fair enough. So I think most of you have already Entered your answer Very good. This should be, you know, see Questions might appear to be little easier, but this is a very good mechanism of You know going through the concepts once again and revising all of that so Very good. So last 10 second guys. I think those who have not marked your answer. You can now mark your answer and complete the process Okay, so here is the last Three seconds and gone. So now let's check whether you have yeah, so most of you have got it correct And that's fine. I still find few people are either Doing it, you know deliberately in terms of let's say they're just marking it randomly. Don't do that so Explanation AB and CR interior angles of a triangle ABC then sign B plus C by 2 underlying concept So we'll write the underlying concept first and then solve it. So underlying concept is first of all triangle Angle some property of a triangle, right? So that you alert in ninth grade angle some property Angle some property will be required to solve this and the second thing which is required is again complimentary angles So knowledge of these two. Yeah, please Complementary angles All of these so a plus B plus C, you know is 180 degrees That means a plus B plus C by 2 Will be 90 degrees That means B plus C by 2 will be equal to 90 minus a by 2 Okay, so sign of B plus C by 2 will be equal to sign of 90 minus a by 2 and sign 90 minus theta is cos theta so cos A by 2 so someone who knows these two concepts will be able to Drive hope this point. Okay, so this is the option and most of you have done it correct those who haven't please take note of the solution and Do not repeat this again. So Where do you go? Yeah, so the updated leaderboard Very good. So the new leaderboard looks something like this very good. Why very good I'll get lunch aren't an up front of Alicia Namish, Surya, Shobita, Anish. Okay. No worries I don't really you know pay that much attention on this thing I will check your accuracy back end and that is more important to me.  Yeah Yeah, think about the question and then answer. Don't mark just like that Could be could be could be some trap Somewhere I think I have to check your internet dear. It's working elsewhere No problem. You can watch the quiz. No problem if you're technically not Able of attending it very good. Take your time People mark and then realize. Hey, this was something else and I did something else So that should not be the condition that should not be the thing Okay Quick most of you have This was again Never mind. Let me let all complete and then I'll explain Okay, so almost everyone has done so if everyone marks his answer we can Proceed to the you know the next step Right, so there are few more who are still thinking about it thinking about it Right, so this was ideal time taken for that should have been within 30 seconds But that's but then initial stages. Please take time. I'm no problem. Okay, so everyone has voted Anyway, so here is the answer guys So it was very very simple and most of you have got it correct. So good. Let me explain So it was fairly simple. Actually, this was you know Appearing to be complicated, but you had to just use underlying concept of again complimentary angles So complimentary angles E ratios right so sign of 81 degrees is simple cost of 90 degrees minus 81 degrees is it and tan of 81 degrees is part of 90 degrees minus Yeah, so caught 81 is caught 90 minus 9 degrees Sorry tan 81 it is right. Yeah, so tan 81 is caught off 90 minus 9 degrees. Am I right? No tan of 90 minus 9 degrees. My bad So tan of 99, right? So now what this is Sorry, yeah, so this is nothing but Yeah, so wait a minute Yes, so this is nothing but cost of 9 degrees and this is tan 90 minus 9 degrees for 9 degrees correct Right, so this was option 3 very very easy once again cost of or let's start from the beginning if you if you are Not comfortable to sign 81 and tan 81. No chatting now Right, let let the things be as it is so sign 81 can be written as sign of 90 degrees minus 9 degrees and This can be done as tan of 90 degrees minus 9 degrees both 81 word Right, and then what do you do sign 90 minus 9 is cost 9 degrees and tan 90 minus 9 is caught 9 degrees Very simple Okay, anyways. Yes, what's happening right? Don't worry. Okay, so here is next readable very good very good Nice to see lots of people coming up. Okay now any any difficulty Any difficulty anyone so if anyone has any difficulty again first step Second step third step. That's it. If you don't you know, just just mark. Just notice this. That's it Isn't it? Okay, next here, please take AC as 8 centimeter guys 8. It's not 6 So it's 8 centimeter AC is 8 again. I'm saying AC is 8 It AC is 8. So let me show you this so that it becomes easier. AC is 8 centimeter not 6. There is some slight mistake AC is 8 8 centimeter 8 centimeter AC is 8 centimeter. Don't take it as 6 Don't take it as 6 AC is 8 centimeter again re clarifying. Yes AC is 8 centimeter. Let me know. So AC is 8 centimeter. I think most of you have done it already Yes, 15 more seconds AC is 8. Please take care. There was slightly, you know typing error So inside clarified that 80 AC is 8 centimeter. Okay. Here is the time's up that the answer was See, right? So lots of you have bought it. Correct. This particular question has direct linkage with next year's Chapters on vectors and other other things. So it's very important to understand this So you now know area if you know Trinometry, you can find out area of a triangle. So This is the thing Right. So B was 90 degrees. So this is B. This is a is 30 degrees So let it be a and this is C and this was given as 8 centimeters Okay, so if it is 30 then quickly if you see this side This side will be 8 sine 30 degrees and this will be 8 cos 30 degrees So you have to be very very fast in this why because let's say this is why and this is X and this is H So clearly why by H is equal to sign 30 sign 30. So why is equal to H times sign 30? Okay, similarly if you see X will be H times cos 30 and then you know the area of a triangle Half into base into height. So base is X and Height is why so half into 8 into First X is cos 30 into 8 sine 30. This was the area Okay, so it's what is this half into let me write here. So half into 8 cos 30 is root 3 by 2 Sign and 8 sine 30 is root 3 by 2. These kind of questions will be typically asked in in case exam so, you know, so be ready for such things so hence is 2 2 and 2 this 8 will go and And So it is nothing but 8 8 root 3 Right centimeter square Right and third option is this option is correct Okay Fair enough. So, please remember. So if you also need to remember like that Let's say the formula now generally formula will be half into H square Hypotenuse square into Sine theta into cos theta whatever is the theta whether this theta or that theta the irrespective of whichever angle This is a formula for area of a Area of a triangle whose hypotenuse right angle triangle hypotenuse and one angle is given half H square sine theta cos theta in NTSC's Remember these formulae becomes very very effective. You were you'll be fast and you will be able to solve more number of problems Okay, great. So let's go back and check the leaderboard. So Right now the current status looks something like this Very good Keep keep the pace going very good guys. No problem. No problem. Okay, Shani is also there in the top 10 very good So we thought we really appreciate very good. Good guys. Let's move ahead and go to the next problem Take your time and then solve Take your time and then solve the top of a broken tree has it stopped touching the ground not figure is not shown I'll show it at a distance of 10 meters. This is the figure. Okay, so the figure was not coming over there So hence I have now shown it here So you can use this the top of a broken tree has it stopped touching the ground At a distance of 10 meters from the bottom if the angle made by the broken part with ground is 30 degrees Then the length of the broken part is so to find out the length of the broken part Take your time Don't mess with the ratios.  What is that? So don't mess with the ratios many a times in such questions. What happens is people Take sine cocosse secant copo secant and things like that. Don't do that So now I'm going back to the original question. So now, you know what the figure is. So here is question so Right, you should draw the figure quickly. So in NTS is let's say such questions come draw the figure quickly and Or let's say, you know, you can do it in the question paper itself if that's allowed So during our time, we were allowed to scribble on the question paper and we used to do that If it is allowed, you can just take the help of the figure given in the question itself and then you can solve No, it's in CBS. It's not allowed NTS. He is little different to you. Just check with them If that's allowed then you can do that Okay, very good. It saves time Right. Okay. Okay. So here is the Final. Okay. So 20 by root 3 Okay. Okay. So great. So, you know, so this is the Current or less is the answer and was very very simple actually very very simple So you have to find out the broken part. Let that broken part be H and The 10 meter anyways given so you don't need anything else. You just need to say cost 30 Was equal to 10 upon H simply and then done right So cost 30 was 10 upon H. So H would have been 10 upon cost of 30 degrees, right? And we know cost of 30 degrees root 3 by 2 that you should be very very thorough So don't forget it or don't mistake here or don't take you know commit any Is played late now can't really don't really know what is the problem Okay, so hence 20 by root 3.  That's most important. It happens at Okay, okay. Yes, so hence hence I did I was pointing on pointing towards that only you will be knowing the answer You will be knowing the approach, but all this off, you know, I don't get me wrong But in all your minds right now it is there. How do I get on to that leaderboard or you know Hence that is creating all this the problem. So just relax. No need. Don't be in the leaderboard Anyways, I'm not going to judge anyone on this. So hence just chill and solve Okay, so here is the next leaderboard Result, okay. Good. Aditya's maintaining the lead. That's really nice. But then this time to shuffling No, no shuffling. Okay. Very good. Next question guys ready Yes Okay, fine. Shall we move ahead? Just five second pause all of you give me a thumbs up. Why all so far? So good any problem all good all good very good. So You're going good. Don't worry about the leaderboard. Just solve 100% correct. That's it. That should be the objective all even if you try only three all three should be correct. That's it Okay, next question Here is a question if x is a cos square theta Plus b sin square theta then so few people are just randomly marking it. I know That's really sad Take time and do it no hurry You're losing it if you're marking it If you're really fast and you have done it no problem, but then if not Then there's a problem. No problem area. What will what will go wrong? Take it? Let it go random Now the could you solve the problem? That's important. Could you solve it? Then fine be happy. No, why why do you care at times it might happen Or if you want you can re-log in or change the mode if you're able to solve that's that's good enough That's the agenda that means the objective is accomplished. So this leaderboard anyways How does it matter?  Yeah more than that in fact, but They will be writing different boards and total in India different board 10 graders, okay Here is the final This thing. So hence, let me see how many of you got it correct. Not bad. So at 28 people Uh, okay. No, no problem Kiran Mai and all, you know, so hence Uh, now let's let's analyze where did it go wrong? Why most of you could not solve it? How many of you got it correct? How many of you, you know Right, okay. So good Good. So let me show you it was very simple problem again So you have to just deploy the values and do it. So let's say x minus a Would have been what is x a cos square theta plus b sine square theta Right and then minus a Isn't it?  Why is it because one minus cos square theta is Sine square theta. So cos square theta minus one is minus sine square theta So that means now you can take Sine square theta common And you will get b minus a This is x minus a part. What is b minus x? So b minus x. Let's write so b minus a cos square theta plus Sorry, then it will be minus b sine square theta Okay, again take b common. So b common and this is one minus sine square theta minus a cos square theta So one minus sine square.  So now what was the question question was to multiply these x minus a and b minus x So x minus a is sine square theta times b minus a And the other part b minus x was cos square theta and b minus a Isn't it? So this is nothing but b minus a whole square sine square theta Cos square theta right and b minus a whole square is as good as a minus b whole square because squaring Doesn't impact the sine change So hence answer was What one b Right, I hope this is clear to everyone any problem here Any problem to anyone All clear any problem Right and if no problem Okay, fair enough. So that's that looks cool. And let's go back to our Yeah, so here is the updated leaderboard guys Well done very good. So question number six is done. We are exactly halfway through. Oh, so now there is some Suffolk. Oh good Nice. So there's a shuffle No problem. No problem. Yep, you know, uh, oh So sharduli was fastest in this one. Good sharduli. Keep it up next Next problem guys is your on is on your screen. Be careful again Now it will be intensive. You will require some kind of calculation. So hence People are so fast. They have just marked something, huh? guessing Most of you are guessing It is humanly impossible to mark it like that But you never mind. It's your call Okay, very good. Take your time and those who are seriously into it Take your time And then mark Marking is not required If you're not very sure Wait for it solve And then mark These are typical ntsc questions Typical comparative level questions. So they will not get to give you a straightforward one. You have to do a little bit of calculations Okay Very good. Take your time No hurry, but if you're marking it make sure that you get it 100% correct Syria get it correct That's it Yeah, very good So that means people are few people are really spending time. That's fine. Very good So lots of you have got it correct. Who could not get it any x here on a kid. Okay anyone else Good good. I will solve. Oh, what many of you? Okay, so now Here is the solution see if a cos cube theta there is a catch in this question I don't know if you would see the catch. There's a three here There's a three here And you know, there is a cos to the power one and two like that Isn't it? Okay I have just a minute Yeah, there was some issue in the question. I don't know how people have got it correct. There was some What is the issue in the question can anyone guess? Let me see if you're really smart those who have got it correct Who got it correct? Yes, where which which power luxe I didn't even know no problem which which power had an issue here Never mind We will cancel that question But which power which power had a had an issue over here anyone can tell me So in the second one cos square should not have been right? Yes So this shouldn't have in the second one. This should not have been the case. This two is creating a problem over here Yes, very good. Very good. So those who are honest, they could not solve It happened with me in my Inmo problem lots of people I have already told you that one question was wrong and it was only Required to prove that it was wrong Anyways, so hence are you guessed? Fair enough. So those who who could guess also Let's let's solve the problem first. So hence problem is if a cos cube theta plus 3a cos If you get such kind of problem in the exam then how to solve it and hence I was telling you the approach the approach was This was indicative enough. What was indicative enough this three and this three? Where have you seen this three? Yep, where have you seen this three? So this is this was indicative enough enough any never mind next was this was m Let me rewrite here so that I can get some more space to solve and then n was a sine cube theta and 3a cos This should be this rather the other way around Right, so this this two has to be there. This should not have been there This one This was the issue here actually. Yep. Okay. So why because if you add Let's say this question comes in NTSC this year So, what will you do add this and why do you need to add because see the question also They're asking you to add see it is indicative of that Right, so if you add you will get the trick.  Now what you have to raise it to individually to two by three So if you raise it to two by three power m by n two by three will be what a two by three And cos theta Sorry, this is minus right so cos theta minus sine theta And two by three isn't it two by three and there was a three already Isn't it this is okay? I hope this is clear to everyone. So this is two don't get confused This is two by three. Is it fine with everyone? This is m minus n right? So this three and this three will go so it will become square term m plus n Hold to the power two by three would have been a two by three and cos theta plus sine theta Again three into two by three. So this three this three would have gone again And if you add both of them, this is what was required right add Add both of them LHS if you add what will be the RHS A two by three is anyways common to both the terms here also here also so I can take common And what is left within cos theta minus sine theta whole square will be cos square theta minus two cos theta sine theta Plus sine square theta. Is it it?  So that becomes two So answer should be two a Is the answer or the solution clear to everyone those who had raised x Okay, so there was Always women, let's say this this happens in the exam. What will you do? It could be possible And you know at the end of the day people are typing it somewhere, you know And it becomes monotonous at times to actually audit also So hence it might happen. Then what will you do? What will you do then in such cases in such cases where there is no way? Let's say there's not a subjective paper then do mark the answer Definitely mark the answer with whatever This thing you can think of so for example If you think that hey if this was two if this was this this two was not there It would make sense then do it because even if so what normally happens is What happened? No, no, no, so what happens is if there is a wrong question Marks are awarded only to those who have attempted In j e and all it happens Okay, if you don't attempt thinking that hey, you know Or because of lack of confidence or whatever Then you know, you might not get the chance because you haven't attempted it. Okay, so that's one thing So hence if you think okay, this should be like that and this should be the answer so mark it like that. Okay, no problem Fair enough. So let's go to question number next So No problem. I'm canceling the leaderboard here. So let's go to the next question NTSC no But in kvpy j e and all that. So quick Warming up everyone is like so fast here. Good. So super fast. No it was Uh, what do you say a question to warm you up in the middle of the session So that you can gain the confidence back. Okay, so Now everyone should mark it correct. See within 30 seconds. Everyone is done Everyone please mark it so that we can proceed to the next So the life will be like that and yeah, Aditya Ups and downs will be there So these are we you know, uh, see in Especially in these exams at least in the next year. It's not in NTSC that will be So in NTSC mostly what will happen or the other exams they will give you variation They will give you a variation, right It happens namesh at times. I there is there might be some bug here. See this server is in us Every everything is under lockdown. So you can have you know, we are able to use it I am really, you know, uh, thankful to that So don't worry about all that just Revise your concepts and make your fundamentals strong. That's the intention Yes, good. Okay. So, uh, uh, what will be the answer? Okay. Yes, here is the answer. It's all of you know it very easy. Oh, still some people That means they are Randomly marking it. So don't do that Yes, there will be but in this there was no catch Yes. Oh, why why that? Why that? This was so simple a question. You can see it and in fact the option also you didn't need to check So first itself was Uh, you know cos a is equal to 1 by secant a and then done Right. No problem No problem, right? So this itself is True. So hence never mind Is it? Uh Now you have to check for all the above but then all the above was not there in the option. No So this is clearly not correct This is a never possible Why sine is 1 by sine so how can that be 1 secant a corte is 1. No, not possible. Anyways Anyways, so fair enough. So let's go back and see the leaderboard now. Okay. So Change change change Okay I think namish missed that question and hence no problem. No problem. You are still there Good good good next question. Please here is the next Question It will not be that easy. So please please please take your time still. I see two people already marked it These people are start people Really good Some random guessing Take your time Okay, so where was that? This is a combination of two things There are two ways to solve it actually But definitely a combination of your knowledge of trigonometry as well as linear equations in two variables. So mixed Real life problems will always be mixed variety Real life problems will always be and you have to solve it in 90 seconds. I can see some people are still struggling. That's fine That means you are solving it Putting it putting more effort great really appreciate Really appreciate that's nice very good And here is the end of the show Right. Okay. So few people got it. Correct. Okay. That's nice appreciating Okay. So here how to solve guess Yes, at times, you know, so in the end. Yes, I'll explain So this was our question of linear equation as well as trigonometry So you have to solve for x and y guys. That was method one There is one more method even if you are guessing it could be a calculated Guess I will tell you. So if you see, uh, what is this? So you can say x is equal to y Uh y times a cos theta divided by b sin theta Isn't it This is x and let's deploy this in the next equation that is this one. So method of substitution for solving Linear equations. So hence if you now deploy a Into x and x was y into a into cos theta by b sin theta correct Is it so this is a into x and then there was a cos theta for this term as well here this term cos theta, right And then minus b y by sin theta And this is equal to a square minus b square. This will give you the value of y How so this cos theta and this cos theta will disappear very good So what next so let me simplify. So this is a square. So this a multiplied by this a will become a squared y by b sin theta Isn't it by b sin theta minus b y by sin theta and this is equal to a square minus b square Isn't it now What can you do? You can take the common denominator b sin theta Like that. So this will be a square y and this will be b square y and this is a square minus b square Correct. So y is common and a square minus b square will be there and this is b sin theta And this is equal to a square minus b square. Now you can cancel these two Right. So what is y dear friends y is b sin theta If y is b sin theta then what is x What was x anyways x was so hence x will be equal to y is b sin theta. So deploy b sin theta Into a by b sin theta times cos theta So this b sin theta b sin theta goes so x is a cos theta Right. So we I got x and y and what was the question question was to find out x square by a square. Let's find x square by a square. So x by a is cos theta And y by b was sin theta So y square by b square is equal to sin square theta And x square by a square is cos square theta. What will be there some? The sum is simply one, isn't it? So hence This was the answer Right Right and and you could have calculated the guess very easily. It could not be minus one. There are two squares over here How can sum of two square was minus one? So I eliminated Is it it so this is anyways eliminated Correct. Next you could have How could you eliminate this See there is something called dimension analysis dimensionally. So if you see there is no a and b term here In this Right. So there is similarly. There is no a and b term here. Right. So hence why would there be it is perfectly symmetrical You know expression. Why would there be any preference to cos and sin? So, right, this is also symmetrical. This is also symmetrical Why would there be one preference to x y or cos or sin? So this is also a one way of solving it Did you understand the symmetry case? So this is perfectly symmetrical. No x by a is equal to y by b and cos and sin Right. So there is no preference given over to x or y here. Also. This is perfectly symmetrical expression So why would this symmetrical thing Should have any preference of one particular t ratio.  So this is called method of elimination Otherwise you could have done you could have just gone for You know, so you can see what should be the value of You know, so that it becomes c it is a something if you see this one a This one a Minus b and it is square square. So that means x cos theta becomes a then my job is done And y sin theta becomes b then the second equation will be satisfied. No Here it says I don't need to go formal way. I told you the formal way But in my exam I would have done like that. I can clearly see what do I see? I see there is a time something minus b time something and that is coming equal to a square minus b square If I just compare these two terms that is a x cos theta Is equal to a square. This is called trivial Solution method, right? So, you know, clearly if I put x equals to a cos theta and it gives me a hint that b is equal to Um, sorry y is equal to b sin theta and I check it here. It satisfies. That means I got it You can Maybe I don't know You never know your board board board is unpredictable. Anyways, so Why do you care? Now, you know you are equipped. Is it is it okay with everyone? Right, so let me see the new You need a board Okay, so Is again Yep, okay. Good next question quick solve it Hmm, let me see how many of you can do this Okay Take your time I really I really am proud of those people. You know you mark. You're sitting only for marking or what? Mark it. There's a there are four options. I will mark one. Okay This is also a good Take your time. You can't see the question. That's something reload reload. There will be a button to reload reload Still time is left reload Oh Never mind. Here is the question you have told me earlier itself within five seconds if the question doesn't appear Nevermind. I will I will now post it like that Okay So. Oh my god may very less the number of people have got it. Correct. Okay X one job or X X please X X X X X X X. Okay. Nevermind. So Now you are getting into the more. These are the typical questions guys. I'm telling you these are competitive level questions You will not get simple ones in the competitions. Anyways, so Fair enough what was to be found out x by y so find x by y. No, what is the problem, right? Oh, that was x Find x and find y Over so let's find x linear equations. I mean I'm not studied. So what is x here? So if you if you take this one and solve Yeah, so so if I cross multiply I'll get tan theta minus x cos phi x cos y tan theta Just correct me if I'm wrong One tan theta minus x cos phi tan theta is equal to x sine phi first equation Yes, right Okay, so hence what will happen so hence if you take x common so tan theta is equal to x common within brackets sine phi sine phi plus cos phi and theta right Never mind now now look at the solution. Don't worry about what happened. What happened now focus on whether you could solve this problem or not Okay, this will be typically a problem in NPCs at least so hence what will be x? x will be simply tan theta upon sine phi plus cos phi Times tan theta can be written as sine theta cost either Okay, so can I simplify this this will be And in fact, you know the numerator also is sine theta My cost theta that is tan and in the denominator. I can take common denominator. So it is cost theta sine phi plus Cos phi sine theta and divided by one cos theta So far so good Why is it is this board appearing to all Nice hello, who's that Aditi is it? You have to just re-log in dear Because you know, I think most of them are able to so never mind Not completely as in this full my My screen is not visible to you. Oh Okay, fair enough. So hence now you can just cancel this cost.  This was x This was x sir wrote on two things Yeah, so I'm right. This is my continuous canvas here. I Hope this is clear to me. It's my continuous canvas. I've just pasted the question over it. That's it. Okay Yeah, you need you don't need any kids sine theta plus five is not required So because you're not learned it you don't require now. Let's find out why So tan phi is why sine theta. Okay, so let me write it here.  This was tan phi. So let's find out why yes, it will cancel out. That's what so hence tan phi is tan phi multiply cross multiply y cos theta tan phi Is equal to why sine theta? So let's take why common so tan phi is equal to y common Sine theta plus cos theta tan phi Am I right if you? You know, so what is why why would be equal to tan phi? upon Sine theta plus cos theta tan phi Okay, and now again if you do this, what is it tan phi is sine phi upon cos phi divided by Sine theta and Plus cos theta Sine phi by cos phi Right. I'm doing a little fast. I Have never physically seen you and except for those you learn what oh again distraction now now this is Sine phi upon cos phi you need you guys need to do a lot of meditation you get distracted so easily Sine theta cos phi plus Cos theta sine phi whenever I look up for any problem in the chat and there is something else Cos phi, okay, so this is the thing now now Cancel right so hence what do you get y is equal to sine phi upon some simple mathematical Trinometric manipulation nothing else cos theta sine phi and my dear friend. What was the thing x upon y? What was to be found out x upon y you have to find out. Let's find out x upon y. This was x and where was why? This was why right? So let's bring both of them together. So x upon y is equal to sine theta upon Cos theta sine phi plus cos phi sine theta and Divide by y so divide by y will be sine theta cos phi plus cos theta sine phi divided by Sine phi am I right so this this goes so sine theta by sine phi is the right you get that All of you good that got it got it All of you got it how to So the solution who asked I showed the solution to you is how you have to so okay I'll tell you what to do You don't need to this is a lengthy question only Intimidating that's it. What you needed to do was express x in terms of theta and phi express y in terms of theta and phi and then This is divine Okay, so express x Yeah, so last step is this only so I expressed y in terms of theta and phi So I got this I express x in terms of theta and phi I got that so x by y will be simply this and thankfully my God's grace I had the same denominator, right? So while you are in the paper No, it's not that. Oh, that's what see why I if I would be solving this in the paper Do you think I will be writing all these steps not needed you know that the denominator and denominator is going to be cancelled Right, is there any shorter way? Yes, there is What would be that way? Okay, so What you can do is Take sign Take values the other way is Other ways take values So let's say you take there's no harm in taking phi as known value theta take phi as 90 degree Okay, take phi as 90 degree. So phi is equal to 90 degree. Let's say So now solve and theta will become what x upon 1 minus x cos 90 0 so 1 and theta is x Okay, okay, and the next is Uh, yeah, but then you'll have to be little. Yeah, so in this case, you'll have to have tan phi tan phi is And 90 is not defined. So you can't take phi is 90 to take some other value 45 maybe So you can your deploy values and do that from there as well. So take values So other way of doing it is in In the exam, you should do this what? And let's say tan theta theta is 45 or phi is 45. So what will be tan theta? And theta is x by root 2 and 1 minus x by root 2 this you have to do very fast, right? So what is tan theta? So pan theta is x upon root 2 minus x like that. And then what about this one tan phi is 1 Right tan phi is 1 phi is 45 degree. We had taken so one is so hence you'll get 1 minus y cos theta Is equal to Is equal to y sin theta? Okay, so what will you get as y? So y will be from this calculation y will be One upon sin theta plus cos theta so fast you have to do why is this what is x from here x is One and then yes one x is x times 1 plus tan theta is equal to root 2 and theta I will do calculations like that faster. So what is x? x is root 2 tan theta by 1 plus tan theta now check which one is valid Right like that you have to do so from here also you can get but then yeah, so you'll get one You have deployed this also so scientific root 2 value should also come here like that So you will get one of the options correct like this. Okay, so this is another way of You know if you're in there. No someone asked me Another one our techniques into my nobody's hey wait wait you understand So what I'm trying to say is in the exam I would have definitely gone through this method because and then I would have been I would have been a little faster here So I was doing it. No, no try and I wish is the one one of the methods because in the end at the end of the day You have to mark it correct. I would have definitely gone this way initially this way. Why because you know It will certainly give me the answer the other the thing was I was going slow here just to explain it to you If you are doing in the exam, you have to be super fast, you know And then you have to skip Steps without making mistake and that happens only when you have solved million questions Okay, so hence all these methods. I Will tell you more other method, you know informal methods of you know Let's say eliminating and all that stuff if you would have known let's say For example, what is time a plus be and things like that? Then you'd have done it much easier way. There are methods. Don't worry. Okay Okay, next let's quickly finish it guys. I want you to go home. Happy. Yep. So next question is Yeah No, I will not stress because that will be the you know, oh my god, lots of people could run any kid Got it correct. Very good. So that will be the You know The protocol you have to solve you have to develop this thing So the coach will never, you know lower down the standard. Then what is the point of doing all of that? Right, so please let us try to ace it ace it within 100 seconds period all of you and this is doable So you have to improve the yes 100 second What what did Gupta suggest later first question question question question come on complete it Let me see One more question to go. Come on. Pick. So those who are not able to see the question This is the question. I guess the values is it legal everything is fair in Competition and war now you're asking I tell you a story now that now that you have you know, so What is meant by honest police officer, you know What is meant by one honest police officer? Is there any term called honest police officer? So you it's like that, right? So you're asking like that. No, there is no police officers Must be honest by default. You need not attach a Honest to this thing is unfortunate that we have to say that it's like should do this he gave He was supposed to be shoes only why should there be a shoot the gay desi? Anyways, so we'll have a debate later on here Most of you have got it wrong and why is that? I don't know Aren't done. Oh, okay. Okay. Okay. Never mind. So so this was a mix of little bit of you know ninth grade identities problem and Trignometry and okay, let me let me show this to you. So sine x plus cosecant can be written as 1 upon sine x and This is 2 Okay, so what can I write? I can write sine square x Plus 1 by sine x is equal to 2 This was it could not have been easier than this. So hence sine square x Plus 1 is equal to 2 sine x What does it mean? It means sine square x minus 2 sine x Plus 1 is 0 Alright, so what is this sine x minus 1 whole square is 0. So sine x is equal to 1 So x is 90 degrees Correct now now put x equals to 90 degrees sine 90 is anyways one. So this is one Oh second 90 is one again. So this is also one. So one plus one is two. How much time was there required for this? So now you understand how the questions will be there will not be straightforward They will challenge your Was it so difficult? So if someone knew how to tackle this and It became an identity a square a square minus v square is Is equal a square minus 2 a b plus 1 equals to 0 from there you got sine square x sine x minus 1 is 0 So sine x is 1 sine x is 1 when when x is 90 degrees And you could have predicted like that also see sine x plus cosy cosy can't x is 2 So don't you think maximum value of sine x is anyways one Maximum value of sine x is how much one Right, so that means automatically cosecant x left would be one so when that when can that be possible? So you could have guessed the x value itself. Yes 90 degree directly. Yes, correct Rn. You could have done this x is 90 degrees Right, even if let's say x is some other degree, but it is definitely true for 90 So you could have just gone with that So if x is 90 sine x plus cosecant x is to that is that is this equation is satisfied Directly deploy 90 here and get the answer quick Right, so you don't need to do this formal way Let's say it was a subjective question. You could have done this, but it is an objective question You could have done like that Is understood by all right, so I could say you know only I was really disappointed this is very intelligent question But see only 22 out of those many Responded right so hence Both are correct in this grade normally you say 90 degree or pi by 2, but you don't require any There is no problem in taking 90 degrees or pi by 2 both are correct No, you will get the same answer next and the final question of the evening Or before that the leaderboard Okay, so oh my god, so many Good, so there is reshuffling. Okay. Cool. Next. So Monisha was fastest here. Monisha was fastest Okay, fair enough next question and the final one Take your time So there are a few people already What? Quality few will be ready to mark with my answer mark mark mark right now press. Yeah, one first person. Yeah, see This is so The hilarious at times. Okay, those who are not able to see the screen here is the question in bigger font Hey, this is not included. This is inclined. Sorry inclined if you have those who have knowledge of vectors can crack it in Five seconds different order. How can that be ABCD? What is a different order here on you get? Options will be in a B and C and D, right? It should be ascending instead of approaching who has created the question. Mr. Booker that is can you just capture the screen and Send it to me on a kid. I will just forward it to those developers What wait a minute.  The time is up Time is up. Is that time up? Okay?  Okay. So never mind those who have anyway, this is last question understand What is the value come on? How many if you bought it correct answer was one meter per second? How many if you bought it correct one meter per second? Those who had who are solved who have already done this vector thingy Would have understood this very easily question was this that there is a ladder This is the wall This is the ground This is the ladder and this is this angle is 30 degrees Making an angle of 30 degree with it A man is ascending the ladder at the rate of two meters per second. So he's going up two meter per second Okay, so the question was how How fast is approaching the wall? Right. So those who have done vectors, I will explain both, you know with vector It is like one minute. So the velocity was nothing but the component along with this Component of the velocity. So let's say this is the velocity or the speed of the man up upstairs or you know Guys and then this is 30 degrees. So this is 60 degrees. So the x component of velocity is the answer So we cost 60 Directly x component. Yes, yes, very good. So that means we into one by two So we was to answer will be one meter per second. This is for those who know vectors. Those who do not know vectors for them How to solve this Those who do not know vectors for them also. It is easy. Let's say The guy in one second the the person will travel two meter up agree Right in one second the person will travel two meter up. So he is going So let's let's let's try to find out one second scenario So in one second the guy has gone up two meters. Let's say this is two meters The question was how close he comes in that one second to the wall So let's say in one second the guy goes up to two meter and let's say he travels x meters towards the wall and This angle this was 30 degrees given anyways. So this is 60 degrees. So don't we know x by To is cost 60. Okay. So x is to cost 60 So if in one second he climbs up two meters, he will move towards the wall by X meters in the same one second that means two into two cost 60 is what? Two cost 60 is two into one by two, which is one, right? So if he moves, what does it mean? It means if he moves up by one meter He approaches the wall by sorry if he moves up by two meters in one second He will go one meter towards the wall in one second. So his feet towards the wall would be One meter per second. Is that clear? Give me why x and what why clear? Clear why all of you all of you, please? Otherwise, I like explain once again. Don't worry Don't worry. Those who want to leave can leave those who want to get more explanation can stay back Those who want to see the leaderboard can stay back Okay, fair enough. So hence I am taking and assuming that it is understood by all and here is the final. Oh Pranav well done. So you are the final winner okay, and Next was Aditya then Alisha from CHK Aniket. Good. Well done. Nana very good. Surya Monish Laksh and Neha. Well done guys. So you would have got your individual Performances in your respective accounts No problem Aditya.  So 805 is the maximum will wait Okay, no problem. Did you learn something today?  Okay. So the next class mostly we will be doing what? What did we do linear equations? So let's do linear equations next Okay, good night folks.
