Hello and welcome to the session the given question says if x-2 into x plus 3 is the GCD of polynomials Px and Qx find the values of A and B. Let's start with the solution. Here we are given that GCD of Px and Qx is equal to x-2 into x plus 3. Now Px is equal to x-2 minus 3x plus 2 into Ax-2 plus 7x plus 3. Now the first term which is x-2 minus 3x plus 2 can be written as x-2 minus x minus 2x plus 2 by splitting the middle 2. Now taking x common from the first 2 terms and minus 2 common from the last 2 terms we have x into x minus 1 minus 2 into x minus 1. So this is equal to x minus 1 into x minus 2. So Px can further be written as x minus 1 into x minus 2 into Ax-2 plus 7x plus 3. Now we are given that x minus 2 into x plus 3 is the GCD of polynomials Px and Qx. So this implies when x is equal to 2 and minus 3 the value of this polynomial is 0. Therefore we have P at minus 3 is equal to 0. Now on replacing x by minus 3 in this equation we have minus 4 into minus 5 into 9A minus 21 plus 3 is equal to 0. Or we have 20 into 9A minus 18 is equal to 0 or this further implies that 9A is equal to 18 or A is equal to 2. Now we are given that the polynomial Qx is equal to 3x square plus 8x minus 3 into x square plus Bx plus 6. Now the polynomial 3x square plus 8x minus 3 can be written as 3x square plus 9x minus x minus 3. Now taking 3x common from the first 2 terms and minus 1 common from the last 2 terms we have 3x into x plus 3 minus 1 into x plus 3 and this is equal to 3x minus 1 into x plus 3. Therefore this can be written as 3x minus 1 into x plus 3 into x square plus Bx plus 6. Now as we are given that x minus 2 into x plus 3 is the GCD of the polynomials Px and Qx. Therefore Q at the point 2 is equal to 0. Now replacing x by 2 we have 5 into 5 into 4 plus 2 into B plus 6 is equal to 0 and this implies that 2B plus 10 is equal to 0 or B is equal to 10. Taking on the right hand side we have minus 10 divided by 2 and this gives us minus 5. Therefore B is equal to minus 5. Hence our answer is the value of A is 2 and the value of B is minus 5. So this completes the session. Hope you have understood it well. Bye and take care.


So hey guys welcome to come again if you're new make sure you hit the subscribe button and a little bell Count below hit the like button. I'm gonna even share with your friends Good job. We have cookies and milk Might be semen. I'm not sure All right guys welcome back to come again today. I'm gonna be going over the loyal subjects action vinyls Dragon Ball Z Mystery figure. So let's take a look at this box Nice picture of Goku on the front Got the loyal subjects logo on the bottom corner with action vinyls Dragon Ball Z corner logo across the top Same thing on The top minus Goku you got one of the dragon balls on The side for those of you who don't know if you hear that in the background. It's my dog crypto He's a Dalmatian He's drinking some water in the background. So anyway, you got fully poseable modern action vinyls Vegeta is every two and twelve Super Saiyan Vegeta two and twelve perfect cell two and two of twelve Goku every two of twelve Piccolo two of twelve and Frieza final form two of twelve with the rare Chase figures being Super Saiyan Goku gold one Goku neon club 28 Trunks metallic One in 96 Super Saiyan Goku metallic one in 48 As you can see here, you got the loyal subjects website address www.loyalsubjects.com Facebook comm slash the loyal subjects co Twitter comm slash loyal subjects Instagram at the loyal subjects Got to we animation Funimation loyal subjects action vinyls Manufactured by the loyal subjects wave to LLC And it is made in China. So let's go ahead and pop this thing open and see what we got inside All right, so we've got a nice little foil baggy here Dragon Ball Z the loyal subjects It is a mystery bag, so you don't know which one you're gonna get until you open it Personally I would prefer to know who I'm getting I'm a big fan of Vegeta So I would really like to get Vegeta, but I can understand why they do it like this So let's go ahead and open it up. Ooh We got Piccolo. Here's his little Card Piccolo is a new Mekyan who first appeared as the son of King Piccolo and An enemy of Goku eventually Piccolo and Goku form an uneasy alliance to fight Raditz Goku's evil brother and after Goku's resulting death becomes Gohan's mentor Until Goku returns from the afterlife to fight Vegeta and Nappa Piccolo following the Saiyans is one of the strongest beings on earth and one of Gohan's greatest role models Here's a checklist on the back And it comes does come with a little baggy. It has one of the dragon balls and a different change of hands The detail on this figure is very nice His joints are a little tight at first, but his head is on a ball joint It can go up and down side to side spin all the way around Not bad. The cape does hinder it a little bit But it does pop right off You cannot take this cape off though his arms are on a ball joints as well they can move up and down and out slightly and then there's Another joint. I don't know how well you can see that. Let me turn this light on real quick. There we go All right, so there's another joint right there Maybe a little difficult To get that to move Then you got the wrist joint articulation and as with his head the hands It should pop off since it got there we go. It's a little tough, but you can take the hand off and Swap it out. Well, let's leave that off for now Then you've got waist articulation Leg articulation they are on ball joints and You got the foot swivel right at the ankle that it looks like And no other articulation to that but the detail on this guy is Very nice Not that Piccolo has a whole lot of detail anyway But it's still nice to have a Figure of him with such good detail. So let's go ahead and open this plastic bag We'll go ahead and put Replace one of his hands It is an opened hand You kind of have to force it. I wish they would make it a little easier but It is what it is Crime and netly There we go. There's one of his hands. I'll leave the other one off and a fist You can see he does come with another open hand for his left hand and then you've got The sixth dragon ball, I'm not sure how well you guys can see that Or no the seventh dragon ball. I'm sorry. I believe I'm not Super hardcore fan of Dragon Ball Z. I but I believe there are only seven Dragon Balls. I could be wrong Correct me in the comments if I'm wrong But it looks like if it's Right in Piccolo's hand just like so See they've got all the creases and folds in his little Outfit it does appear to be a little bit of a bad paint job along the belt I'm not sure if that's design or if that's actually a bad paint job though The rest of it seems to be a pretty good paint job hardly any paint bleeding at all nice bright white colors nice green Very nice figure. He's gonna go well with my masters of the universe loyal subjects minifigs Gonna go right up on my shelf and I'll probably review those a little bit later because I currently have a evil in triclops and Trap draw so if you want to see that review leave a comment and I'm sure I can accommodate We do already have John did a review on the masters of the universe loyal subjects line for He-Man Skeletor Beast man in there and Stratos So I believe he had he man Stratos Skeletor and Beast man, so I Could probably go ahead and accommodate you guys do a review on evil Lynn Trap jaw and triclops in the near future So there you have it Loyal subjects minifigures Dragon Ball Z Piccolo so head up to your local store Walmart. I believe Target has them Amazon of course Loyal subjects comm I believe has them For sale on there. I know that they manufacture them But I'm not sure if you can actually buy them off the site or not.  I'm Shannon and have a good one


Right, OK. So I will come back to the virtual comport driver because we always have issues with that at some point because there's so many different variations of PC in this room. So what we're going to do now to create our oscilloscope, we will use the ADC to send the data over the USB. To trigger the ADC, we're going to use one of the timers. So we're going to set one of the timers up to periodically trigger the ADC to take a sample. The ADC will then use the DMA to load that into a buffer inside the memory. So the first thing we have to do is set up a timer to generate the triggers for our ADC. So what we're going to do is use the internal clock that's available inside the SDM32. We're going to configure the timer with a prescaler so that we get, I think it's a 10K interrupt, or 10 kilohertz interrupt. Then we'll set the compare value up so that when our counter hits that compare value, we'll then go out and trigger the ADC. So first thing we're going to do is select new project. So you can either do it from the menu up at the top or from the big new project button in the middle of the screen. This will present you with the selector guide for the microcontrollers that are available. Now there are different ways you can select your microcontroller. And this is a very good tool if you want to rationalize about 1,000 different sales types we now have for what you need in any application. You can either do it by board selection. So you can select it from the boards, where you've got nuclear boards, discovery boards. I think you'll find this discovery board in there if you want to use that channel. Or you can select it by specific peripherals. So if you need a TFT controller, or if you need ethernet, or five U-hertz, you can select it on this side. And it will reduce the number of items in this left-hand side. We know exactly which device we're going to use today. So we're going to select the series as being F7. The product line has been F7X6. And the package has been TFBGA216. And the package you want to select, so the device you want is the 746NGH. So that's the device that's on the bottom of your board. 746, yes? Ignore that for now. 746 is what's on your board. I have been advised that IAR now have the 746 included if you've all got the latest version of IAR, which you must have because you've already been compiling examples earlier today. So that should be OK. So everyone's telling me they've got the Pingrid array out, apart from one gentleman or the other who's just doing the same as you, upgrading. All right, I'll catch you up in a minute in the corner. So when you go into the PIN diagram, I'll go into this section here because we can see it. On the left-hand side, you will have all the periphery that is on the device. Now, some of these peripherals will have yellow icons. Some will be red icons as well. If it's a yellow icon, then you now have a conflict with part of another peripheral that's already been assigned to PINs. So some of you have selected the Discovery Board as your starting point, which means you've probably got quite a lot of yellow icons actually on that side because each PIN on this device has about six to nine different functions. So it means one of those functions, because you've assigned it to one peripheral, means it's no longer available in another peripheral. So you have to go and have a look to see what's in that each individual peripheral. One little element would have gone red when you expand each of these peripherals. You'll see that one part's gone red. So if you select, say, ADC 1 as a perfect example, you might find that some of the PINs have gone red because they're now assigned to a peripheral and you can't use them as an ADC channel anymore. So firstly, we're going to assign our timer 2. We're going to select timer 2, please. We're going to use the clock source for timer 2 as the internal clock, and then we're going to use channel 2 to be output compare with no output. Remember, we're only triggering the timer so we don't need the PIN. So we don't need the actual output PIN. We just need the timer to actually trigger something else. So it's output compare with no output. It yellow means it's half assigned inside because it is actually connected to the Arduino connector, which is what we're going to use in the example. So we're going to plug something into the Arduino connector at the end. So that's why it's yellow because it's physically hardwired to something at the moment. So hopefully it should have gone green now when you've done that. So we've now set your timer up to generate the clock source and the connection to the ADC. So we now need to set the clock source. So on the discovery board, we have a 25 megahertz resonator. So you need to go into the resetting clock control module, so RCC. And we need to select the HSE to be bypass the clock source. What that means is we're bypassing the internal clock source in the STM32 because you're using a resonator outside. So you're going to bypass our clock source that's inside the chip. So we're just going to feed it in. So that's what you've got on your board. So we need to bypass the clock source. Once you've assigned the clocks to be 25 megahertz, if you select the clock configuration tab from the top, near where it says pins, up at the top of your screen, and if you've assigned your bypass correctly, your 25 megahertz connected to your HSE should be blue now. That should be a blue. And hopefully it should say 25 megahertz. So once we've connected our HSE to the chip, we now need to select the multiplexer so it uses the HSE to feed the PLLs. So you need to change the dot from HSI to HSE so that you're feeding your PLLs with your 25 megahertz resonator that is on the outside of the chip. Once you've done that, you then need to select the PLL clock to be the source for the system clock in the multiplexer. So you need to pick your PLL clock to feed your system clock. And you should gain two red dots over this side. So some of you have probably got red dots dotted all over here now with PLLs and things like that. What you now need to do is type in a frequency into the H clock box. And to make my life easy, can we use 192 megahertz please? Because 192 is very easily divisible for the 48 megahertz USB clock I'm going to use. When you hit enter, it should automatically reprogram all your PLLs to be the correct values. So now if we move over to the configuration tab, we now need to go and configure our pre-scaler values for our timer two. So if you select timer two, you should be presented with a box that looks like that. Perfect. So what we're going to do now, we're going to configure so that we generate our nice square wave so that we trigger on rising and falling edges of the output compare. So to do this, we are going to use a counter period of 10,799. My frequencies are slightly out because I've not taken 216, but it'll do for what we need to show. It will work. So if you set the counter to be 10,799, and then down here in the output compare channel two section, we need to set it to toggle on match. So that means we'll toggle the low to high on the PDWM output every time we get a match. And then we can okay that screen. So that's your timer set up now to generate the square wave that we need to do the triggering of the ADC. Timer number two and channel number two. So the mode is toggle on match. So the next section is, we're now going to configure the ADC so that it takes our trigger event we've just created to read the ADC channel, copy the data register via the DMA into a memory buffer. So this is what we're going to do now in this section. So to do that, we need to go back to our PIN diagram because we need to assign an ADC PIN now.  We don't need to do anything with the clocks for the ADC. It's all coming from the system clock. So if we go straight to our configuration tab and select ADC three now so that we can configure the ADC three peripheral. So that means you should get a screen that looks something like that displayed with all the settings for ADC three. Now there's quite a few settings to go do inside the ADC. The first setting we need to do is enable the DMA. So it DMA continuous requests needs to be set to enabled. So that means every time we trigger an ADC reading, it'll then trigger the DMA to move the data out of the data register. Next, we need to set the trigger conversion edge and this needs to be set to rising and falling edge. So we want to trigger on both rising and falling edges and then directly below that, we need to say that we want to do timer two, capture, compare two events, I think it is. Capture two events, I can't remember exactly what it says on the screen. So we've now linked our timer two on rising and falling edges to the ADC. Then you will need to expand the rank function, change the cycle time or the sampling time to 144 cycles. So if you expand the rank command, you should find sampling time, which you need to set to 144 cycles. We all manage that, okay. Next, we need to go to the DMA settings for the ADC. So we're going to click on the DMA settings tab at the top there. So if we go on to the DMA tab, so we now need to set the DMA up to take commands from the ADC. So the first thing we need to do is add a channel. You click the big add button on there. You then need to select ADC free as the request. We're going to use it in circular mode. So we need to change the mode into circular. So we're going to continue, we go round and round with the DMA to do this request. And we need to increment the memory. So you need to tick box to increment the memory. So we're going to fill a buffer up. We're going to go round and round and increment the memory to load up all this information into a buffer. We need to set our word length. So it's a 12 bit A to D converter. So we need to set it to be half word data width. And then you can select okay. We've then configured the DMA to take the reading from the ADC and load it into a buffer.


Let's go over some little Q&A. Ah, right. Yeah. Travis says, Rob can do what Rob wants to do. For me, it's a savings account. I'll hand DCN to 50K. I don't trade. That's a pretty good plan, too. Can't beat that. And that's your plan? Looks good. Rob's always so bullish. No. No. I've had a nickname for a while now. Negatron. So, yeah, we'll see. Not a very optimist prime. In the long run, I am. But the short term, I'm like, I don't really know. So that's why, like, even as bearish as I was, you know, and we talked about this NFA, I'm still buying Bitcoin. I'm still buying the altcoins because in my mind, I'm just thinking myself, the biggest gains I ever had in crypto was Cardano and Chainlink, quite honestly, and Theta. It wasn't Bitcoin. It was a very safe play. I asked myself, why would I step away from these massively low prices and get them now? Because I don't know what's going to happen. I mean, who knows? Who knows? Google could come on and say, you know what, we're partnering with Theta for data storage because we have a real hard problem with collecting and having all these warehouses and we just can't have enough cloud storage. We need Theta to come on and we have a massive partnership. Which, by the way, quite honestly, they are one... Google are one of the node operators. So, just take that as it were. A little Theta plug for everybody. All right. So, that's me. It makes me nervous. I'm nervous too. Meme is here. Tesla's here. Hodeldo Panics is Ada. Sure. Ada has, in my opinion, hands down the best-thinking experience you're ever going to see. And people will say, no, but Ethereum. Like, have you steak with Ethereum?  Well, liquid-staking, Rob. Yeah, okay. But still. Yeah, I just think Ada did a better job. See? Crypto-sound. Everybody's like, oh, Rob's bullish today. And he's always like, oh, Rob's bearish. What are you going to do? Look, I've talked about my friend Alex on here for quite some time. In our sports facility, I always bring Alex out and say, hey, Alex, we have this idea. What do you think about it? That's not going to work.  That's awful. I will run 10 ideas by that guy. And when he says one idea is good, I'm like, that's a winner. Let's do that. It's the same thing with me.  And they say, Bitcoin's going to explode tomorrow. Look, when I get super bullish, you know it's a bull market. That's all I'll say. Hey, Papi. Congratulations on the retirement. Good for you getting out of the army. If you don't like grunting at Wimbledon, don't get in the crypto. Carossus, Carossus, and Djokovic are playing, I think. Nobody tell me the outcome. Rob, would you start to buy chilies now? You know, I used to have chilies on this platform called Voyager. Voyager was a great platform. Worked until management decided to give three arrows capital $640 million uncollateralized loan because they're geniuses. I used to buy chilies on Voyager. And then I got 35% back. And they liquidated my chilies. What are you going to do? Would I buy it? Sure. I like the whole aspect of being able to, you know, put that into massive sports leagues and facilities and saying, hey, if you want to be voting on what's going to happen with this soccer team or this football team or this baseball team and chilies, it seems pretty cool to me. I don't know what's going to take off. I think now we're in the phase of, like, all these businesses or all these crypto platforms. It's not just white. It's not just a white paper and a prayer. Now it's like, what are you really doing? What are your revenue? How far are you expanding? And not just because you say you've done some things. What have you actually done and are doing? Because remember, small businesses, most will fail. It's in the first five years. And these crypto projects that they come out, a lot of them are going to fail too. So really have to come down to what do they actually do? Who's adopting it? Who's using it? What's how? Like I talk about. When I take a look at products, I always look at the cut, which is how big is the community? Are they growing? Are they expanding? Are they have regressions? What's the utility? What does it actually do? Is it a me too type of thing? Is it actually work? What is the team done? The T? What is the team done? What have they done before to get to see what they're going to go through? And then of course, what are the tokenomics? CUTT. Community utility team and tokenomics. Yeah. Are they in Bitcoin? Oh my God, Bikki's here. Well, Bikki. Mark says, Bitcoin deniers are poor for a reason. You know what I'm going to love? When all the Bitcoin deniers come in and they say, ah, it's a Ponzi. All right. It's, you know, tulip mania. Or, ah, it's going down. I'm like, have you, do you, can you compare this to the traditional market and see where things are going? Did you know that the biggest asset manager, which is BlackRock with roughly 10 trillion assets under management wants to do a Bitcoin ETF because they believe in Bitcoin, the underlying technology. Do you understand that there's also ETFs coming on in Australia and Europe and there's been bunches in Canada? Do you get that? Or do you just not, just don't want to learn? Yeah, that's probably what it is. I mean, let me rephrase that. I would think that in my mind, but these days I'm getting kind of tired of educating. I'm just like, eh, do what you want, man. I know where I'll be in 2024 or five. Ooh. Chris packs. Buy high, hold bags forever. Yeah. And NFR says I only sell a little. Yeah, sell a little.  Like even when we go to a blow off top, I'm not selling everything. I'm selling roughly 80%. And then go, I'll never sell all my crypto. I mean, who knows? Maybe Bitcoin becomes the next world reserve currency. You think I want to give up all that Bitcoin? Might be who needs to hold on to it a little bit. And if you're asking yourself, well, how does that work? Great question. There's a link in the description of all my videos. And I say, why and when I'm selling 80% of my crypto in 2025, maybe 2025, we'll see. But there's just the indicators. It might be earlier. I should probably retitle that actually. And then, yeah. And then also, if you want to find all those videos, there's a website and it's called Dan teacher's crypto and it's 100% free. All right. What I miss. Inspector Ape or you're selling, I'm not selling anything now. I'm selling all those ranges. So not yet. And this is what it looks like. So the range is for risk bands, which you can find a Ben site. Yeah. I'm probably sell a little bit at 0.6, 0.7, but the majority of the selling is coming down here. And those are very high marks. Like this 0.7 to 0.8 has only been in that range of points history for 125 days. 0.8 to 0.9 has only been 80 days. And 0.9 to 1 has only been 18 days. Once it gets there, hopefully it gets there. I'll be selling. I mean, 12 in 12 years has only been 18 days. Come on. Come on. Come on. All right. doozy and we are in agreement. I still feel there should be another huge dump before the bull market. I sure hope there is. I know everybody thinks to like, we want the price to go up. I'm like, do you, do you really, does everybody here think that they bought enough of crypto or digital assets or Bitcoin? They're like, you know what? I bought way too much. Or you think yourself, man, I just wish there was one more opportunity to go down. And now you can take the emotion out of it. Time and risk bands or some people like to do it by fear and greed indexes, whichever way you want to do. I did okay. I could have done better. We could always do better, but it's like a Baron Rothschild said, I made all my money by never buying the bottom and never selling the top because it doesn't matter. You just want to get close enough as close as you can. That's, that's, that's my goal. Oh, I'm sorry. Ross Hutton level headed perspective. Thanks, Ross. I think you're in good company. I've been away on vacation and going over the last weeks. Not really. Not really. Alex Machinsky is in jail, which is pretty great. I had Simon Dixon on and man, that guy, we were before. Well, I brought him into NFA live as me, Ben and guy. And during that, that, that show, it was, it broke that Alex Machinsky was, was arrested. You should have seen the Simon's face after we got done. Like, well, his face in the, in the green room was pretty good. But then when we like separated between the NFA live and the, in the, the talk, man, that guy was, I've never seen that guy smile so big. There are two good kiosks is robbing into precious metals. I would take a look. Yes, I buy gold and I have that in my, I trust IRA. I don't see why anybody wouldn't own gold or silver. I think it's a, it's a great hedge and it'll probably do quite well. It's a good store of value. I still believe it. The fact that Rob is not a chosen criminal. I used to light chilies. It seemed like a pretty good, pretty good project. Holy smokes. Listen to this everybody. Piper says, I had my XRP in an inverse contract, three X long DC, my, my entries on pullback took a while to catch it, took an $11,000 profit this week and closed it. The trade was using XRP and an XRP trade with XRP profit. Man, that's crazy. Check out channels like that. Army Piper Army puts your, your YouTube channel in. If you guys like to trade, I'm not a trader. You should not follow me. Listen to anything I do because I don't trade. Those are smarter people out there. Walking with pause dog training. I heard your voice watching James the other day. I had to comment his goals or not your goals. That's right. Exactly. Ooh, big thing coming with James's channel tomorrow. You might want to check it out. Just saying. Maybe a little DCA. Rain Vosh that isn't July, August, September supposed to be turned around in the market. It's a great question. And let me show you something. September historically is the worst month in traditional markets and in the crypto market. Let's see. Charts, crypto. This is it. So there's a chart here. Monthly returns. If we just take a look at September, hopefully everybody can see this. Let me put this in. So look at this. What do you notice here? And this goes by years. 2023 is in the column. The columns on the left side are the years. 2023 all the way to 2010. And we can see that in all honesty, February is a great month year over year, regardless of four-year cycles. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. 10 months out of 13 years it's green. Probably one of the best months. November, 1, 2, 3, 4, 5, 6, 7, 8, 8. Not too bad. December, not so much. But I want you to take a look at September. In the red is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Again, not the greatest months. August isn't much better. 1, 2, 3, 4, 5, 6, 7, 8. So if you want to historically take a look at it, that's it. But you have to kind of break it down into four-year cycles. So to me, the having years are 2012, 2016, 2020, then 2024. The year before those having cycles, to me are accumulation years. So 2023, it's been a pretty good year so far. 2019, 1, 2, 3, 4, 5, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 7. So always look at those four-year cycle months as they pertain to everything. But again, August and September, not the greatest. And let's see. In 2015, how was it? It was actually green, I'll be damned. 2019, it was red. It was red a lot. 14%. 2013, no. 2015, yeah, 259. So just be aware, this is what's happening. Middle of the road. CryptoGolfers is on my website. It's free now, but will it always be free? I have no plans to monetize my website. Dan teaches crypto. It's always been free. I think we have over 40,000, 45,000 users now. It's not bad. If I just want to charge everybody a buck a month, 45 grand a month, that's okay. Yeah. Dan Ellis says, didn't Simon also say he sold Coinbase his security license back a few years ago? It was a broker-dealer license, as a matter of fact. And we talked about this many times, me and Simon. He's been on the channel probably six, seven times. But yeah, for his company Bank of the Future, which had small investments, but they, you know, like Kraken and Coinbase and Bitfinex and da-da-da-da. ICO for Ethereum, stuff like that. But they did a broker-dealer license, and they sold it off to Coinbase. And actually, he didn't have to make a good point about securities. He said, you know, I know where Coinbase is coming from when they're saying that, you know, the SEC isn't being very fair with them. He goes, but in all honesty, they should be doing more for that side for their broker-dealer license because that's what's required. He says they're not. He goes, but that still doesn't excuse the fact that the SEC has given them no help whatsoever, which I could see. There's always two sides to his story. Thanks for having me get together. I got my grandson here this week. So probably a week after that. Let's do that. Rob does show Ben's website quite a bit, but Ben gives Rob free access to his website, and I steal all his stuff, so it works out pretty well. And it is an affiliate link. So if everybody knows that, just so you know. Yeah, that's a good one. I should put, I'm not your dad, as number one. Doing life. That's it. And the cryptiverse member used the link, 10% off the first month. Just saying. Yeah, the green screen in Puerto Rico is crazy. Overly bearish for no reason. I'm just cautious that's all. I think that's it. Gary says Ben does not have emotions. He cannot be bitter. Let me tell you something that's not accurate. Before the show of NFA Live, I wish I could record the talks that me, Ben and Guy do before NFA Live. They're quite funny. Ben's a pretty funny guy. But I just can't. One of these days I will. I'll sneak it in on him, but that's it. Anyhow, guys, it's been 34 minutes. I'm sure there's other stuff you can do today, but that's just what's going on. So, look, like today's video, thumbs up, consider subscribing.  Just make sure you get information in because the next two years, 18 to 24 months, is going to be crazy. You need to keep up to date, especially what's going on. So that's it. So thanks so much for stopping by. I appreciate you. And I'll see you guys on the next one. Adios.


Good morning, everyone. I'm Allison at Roberts with the California Energy Commission's media office And we are here today to release a major assessment of climate change in California Before we get going a few rules of the road and some thank yous We want to thank especially Cal EMA for hosting this event Among those who deserve special thanks are Tina Walker and Justin Short for making everything in this room work properly And I want to especially thank Mark Gillard Ducci for his gracious The secretary of Cal EMA for his generous Welcoming of us. The news conference is being webcast and the video will be available on the Cal EMA site It may take a couple of hours to archive after the press conference concludes When our speakers have finished you will have an opportunity for one-on-ones here in this room And thank you and now with no more delay. We shall commence. Thank you Good morning. I'm John Laird the secretary of the natural resources agency. It's my pleasure to welcome you here today As was just mentioned We are releasing a new assessment of climate change today that's embodied in 34 different vulnerability Assessments the significant thing about today's release is that while there's been much science on climate change This ties that science to the vulnerabilities across California and how we have to start thinking about how to adapt for example We have done science before these reports on sea level rise Almost all science Pertaining to California says that at the end of the century we will have sea level rise between five and six feet For the first time this says here are some things that we need to start to be thinking about To adapt to that sea level rise whether it's airports in the San Francisco Bay area the entire Delta ecosystem Gravity feed Systems and sewer and water that are tied to the current sea level and not to the future sea level All these things are things we have to think about in moving forward additionally There are ones that Some of the speakers will address coming forward But when you look at fires What the change in climate will do to fires how it ties to our electric transmission system There's whole host of issues that relate to that and those are the kinds of vulnerabilities that now we're talking about in terms of the science because just as With greenhouse gas emissions there was a big push to have individuals in California and across the country Understand how their actions deal with it and what they can do to respond to the actions We are looking at Climate change and what we have to do to adapt and the individual decisions that people can make to adapt This is very significant also because it comes on the heels of the stories in the last two days of scientist Richard Mueller Changing his position no longer being a climate change skeptic But agreeing with the bulk of science from every academy of science across the world that climate change is A reality it is actually happening So that is a significant thing today is that we're talking about how to adapt How to tie vulnerabilities to climate change and how to get Californians at every level of government and individuals to think about this and start to make their actions match What we have to do in a change in climate in California We also have with us today, and I want to acknowledge Daniel KN from the Scripps Institute who is a researcher that contributed much to this report And who traveled from San Diego to join us today, and now it's my pleasure to introduce Ken Alex who's a senior policy advisor to Governor Brown and also director of the office of planning and research Thank You Secretary Laird. Good morning everybody You know we accept that Cigarette smoking causes cancer, and we accept that HIV causes AIDS and as a country and and as a state We make decisions policy decisions based on those scientific determinations We are not there. We are not in the same place with climate change But California is working to change that and here in California We do make policy decisions based on the science Governor Brown actually reads the science And he takes it very seriously. I know at a very deeply personal level He wants to do something about climate change and he wants to see California take a leadership role This set of reports that we should note is funded by the Energy Commission Does not paint a rosy picture Climate change is here now in California We need to adapt and we need to understand what that adaptation requires and what the vulnerabilities of Particular communities are We understand now that we have great threats fire that we've heard about sea level rise drought flooding These are a series of plagues, but we're not helpless We are now able to look very much in detail at the kinds of things that we can and should be doing in the state of California We're going to be issuing Climate adaptation planning guide later this year to help local communities To adapt and to work with the science In addition, we're working with a series of regional entities in the in the large metropolitan areas around the state And with local communities and you'll hear a little bit more about that today as well and Calima is one of the entities That's doing very significant work in this area In California as most of you know, we're moving forward on a series of issues dealing with improving energy efficiency water efficiency in Increasing the amount of renewable energy moving to a low carbon fuel transportation system these are Part of the response to climate change, but they're not it because we have already Done enough as humans to change the climate and we have to deal with the impacts that that are coming so We take hard in California what we learn from science and On behalf of Governor Brown, I want to thank the energy Commission I want to thank the peer program which is a very under reported entity in the state of California that does incredible science and Thank everybody involved with this set of reports. So with that, let me introduce Bob Weisenmiller Who's the chair of the energy Commission? Thank you Thank you I'm not not only the chair of the energy Commission, but I was appointed to the scientist engineer position at the Commission and Certainly, I'm very proud of the scientists that we have in the peer program For this assessment. They're put together We scientists know that climate change is and will be significantly affecting the stage energy supply and demand system the research in these assessments further understanding of these impacts for Example researchers found that the electricity system is much more vulnerable than we had thought One of our responsibilities is to make sure we have a reliable power system So we will use this study to determine how to reduce these vulnerabilities in our power system One example is that we indeed are looking at higher temperatures temperatures have risen Certainly in the last hundred years looking over the next hundred years. They're going to be increasing at a significant rate One of the impacts of higher temperatures in a more severe summers will be greater demands for electricity in the summer and This report these reports indicate we could see up to an additional gigawatt power of our demand in peak periods in 10 years certainly going out To the end of the century we're talking about much greater numbers another up to 17 gigawatt hours And one of the things we've done this year is we actually when we Adopted a forecast for what the state's power needs are We incorporated the impacts of climate change in that forecast and that was the first time a public agency has Recognized that fact again This is based upon the science and we need to incorporate that in our planning to make sure we have a reliable power system Certainly one of the other impacts is hydropower, you know historically We've been able to store hydropower as snow in the Sierras looking at climate change unfortunately, what we're seeing is that Basically, we're having that snow melting earlier. We're having runoff earlier It's shifting that hydropower production out of our summer peaks into more of the spring time so again that will Aggravate our summer peak load issues having less of that valuable hydropower in the Sierras We also are seeing it in the transmission lines Again as you go to higher temperatures and look at a whole Electric grid system that will result in greater losses of power and those greater losses What we're seeing what the scientists are estimating is that by the end of the century that could be an additional Seven to eight percent losses in those peak periods So again that will aggravate and providing reliable power in those summer periods And we have to find ways to ameliorate those effects But along with the challenges we're seeing there are also opportunities and One we're trying to build that into our thinking for instance The scientists found that some of our key transmission corridors coming down from the Pacific Northwest and Moving into Los Angeles Los Angeles metropolitan area are going to be more vulnerable to increase fires and One of the ways we can try to address that is by having more locally generated electricity instead of bringing Power in on the high voltage lines from out of state or some of our remote areas we can also address that through micro grids and micro grids are essentially Many utilities that combines supplies and to meet demand based upon smart electronics And we're putting that in areas where we need high reliability of power places like University campuses military bases, you know data centers So basically with that modern technology we can ameliorate some of those impacts The other thing we're finding frankly is that we need to Really continue both adaptation and the mitigation route that we're doing We have a various serious effort in California to reduce greenhouse gas emissions through energy efficiency Renewable resources and at this point. We're also looking at electrifying the transportation system The governor has a recent mandate for zero electric vehicles again We are transforming that whole system and as we make those transformations It's an opportunity to also look at how to adjust the designs For example, a lot of our electric utility system was built in the post-Korean war period or in the lbj era And so that's at a period now where it has to be replaced And so we will be replacing that with smart technology so they can better adapt to the situation that we're Confronting with climate change Certainly as we move forward This science will again really underpin some of our activities and we'll try to deal with vulnerabilities another example Is we have this historic study on the Bay Area and one of the things that tells us is What the impacts are of flooding the locations in the extent and that will allow us to look at some of our energy Infrastructure things like power plants things like transmission lines gas lines and start to try to adapt those So that we can deal with those consequences over time I would also like to note along with these historic studies I would like to call out the city of Los Angeles has also done its own study recently under the mayor's direction To really look at what the impacts will be at a local level down there of climate change and Starting to build that into their planning and again I think the challenges are enormous But certainly this state has the capability to rise to those challenges and with these types of studies We're going to be prepared and again certainly we will use these in the energy commission planning to Drive our planning so we can maintain a reliable grid, but also to really use this as a way of planning our research So with that I'd like to introduce Chief Ken Pilot, director of the California Department of Forestry and Fire Protection Thank you. Good morning. Thank you firefighters certainly know The impacts of climate change and they know what it's like to fight these fires on the ground And they must have the right tools to prevail and be successful to protect California and its resources And the citizens that we serve The studies that we've talked about today are that providing the tools we need to further these plans to prepare California and move us into the future the risk that climate change brings More frequent and more intense wildfires Longer fire seasons and a decline in the health our state's coniferous forests We really need the public to understand that these are not changes. We're talking about in the future These changes are occurring now. We're experiencing them now some of the things that we're already seeing Disease and pest infestations in our forests that make them more susceptible to damage from insects and drought We're seeing longer fire seasons on average two months longer in many areas of the state than what we've seen In previous years and in previous decades We're seeing fires in some areas that are more intense And they some areas particularly in Southern California We're seeing fire seasons that can last year-round even in what we would consider to be the wet months of January and February most disconcerting I think for us in the fire service community is the Rapid increase in the number of large damaging fires that have occurred in recent years of the 20 largest fires that have occurred in California the most damaging fires 11 of those have occurred since 2002 Up to that point we were seeing on average maybe one damaging large damaging fire once every decade But to have over 11 occur since 2002 truly tells us that something is changing and we know that The evidence tells us that we need to have a obviously a strong robust emergency response system in the state and working through under Mark Geller-Ducci's leadership in our mutual aid system and the state's emergency response plan And all of the local government state and federal resources that are available We need to continue to maintain and support that robust system But emergency response isn't the only aspect to deal with this changing environment We also need to get ahead of the disasters ahead of the fires before they occur public education is key We have got to be out educating Our citizens in california of the impacts of climate change and what it's doing For the individual residents the things that they need to do to prepare all the things We say every year about fire season defensible space preparing your home evacuation plans All of those things are part of this process in addition to public education We need to be focusing and double our efforts in treating the vegetation and the fuels in california that are contributing to These large and damaging fires california has a strategic fire plan that clearly spells out the steps that we need to take And I really want to thank the energy commission and their leadership in working with the governor's office the administration Cal fire and others to work on incentives and alternatives to deal with fuels biomass and other things that help us Create defensible space fuel breaks and treat vegetation as we work through these challenging times It's evident to us changes occurring and studies like those that are being released today are key In helping us move Forward to to prepare california With that I am honored to introduce one of the researchers who contributed to all of this vital work Suzanne mosier scientist from santa cruz associate with stanford Has dedicated many many years to furthering this information in these studies and with that Thank you for that introduction chief limpin lot and good morning ladies and gentlemen here in the room and across california It's my great honor To speak to you this morning on behalf of the more than 120 scientists who have contributed to california's third climate assessment Some 26 research teams from the state's finest research institutions have contributed to more than 30 studies That we have tried to summarize as best as we could in this little brochure that you have received that is on the web Our changing climate 2012 And it basically spells out what our new understanding is of what climate change might mean to california I was told I have about five minutes to speak So i'm not going to pick just a few findings from that It's already difficult to summarize that great work But what I want to do instead is to highlight the key innovations of what do we know now From this assessment compared to the other two assessments we've done since 2006 In the most important thing that I would say and you've heard this already Through the previous speakers is that this is science that responds to what decision makers are asking for This is not just you know sitting in the lab and trying to figure out What would be interesting to us as scientists to understand we're trying to inform the public We're trying to inform decision makers with Valuable information that they can use in their decision making and planning So let me highlight those three key innovations First managers and planners said they want to know How likely certain climate changes are so for the first time in this assessment We made substantial progress in moving toward the likelihood of climate change projections of sea level rise projections What is the probability of certain? Levels of climate change to occur So in other words if we assume a particular scenario of greenhouse gas emissions going forward Then how likely is it a coastal manager? For example might ask that a certain amount of sea level rise will occur at a certain time in the future Or how likely is it a farmer might ask that we still see freezing temperatures at some point in the future How likely is it a public health department might ask that is certain that we will get extreme temperatures Or a particularly long heat wave in the future So the third assessment for the first time produced this kind of probabilistic likelihood information about climate change Now it's important to Reiterate that these likelihoods depend on the societal choices that we make today The future might be worse or better depend depending on the choices that we make We may cut cut back the greenhouse gas emissions more than we currently plan or less And that will change those probabilities But based on the best information we have the best models we have and Assumptions about those future emissions that is what we can say now And it's easy to sum up what that all adds up to which is that the more heat trapping gases We emit now and in the years to come the more likely is it that we will see very unpleasant and in some cases outright dangerous conditions for california Let me turn to the second Innovation in this study and it's embedded in the name that the third assessment is also known by which is the vulnerability and adaptation study in 2009 the when the california natural resources agency released its first statewide adaptation strategy You may recall that it asked for an um a comprehensive vulnerability and adaptation study for the state And that is what we did So here again, we're responding to what decision makers are asking for We did not just as in the previous assessment focus on potential climate change impacts Not just on the climate and how that might possibly impact natural systems like agriculture or ecosystems Or human health or you know any of our communities what we did instead is we looked at Vulnerability and I want to explain that because it's an important distinction between just looking at potentially what might happen vulnerability means What exactly is exposed on the ground to those climate changes that we're projecting and if that climate change unfolds How severe might the impacts be how sensitive are we to those impacts and then thirdly What can we do to cope and to adapt to those changes? And if you take exposure sensitivity and coping capacity adaptive capacity together You get a true sense of the vulnerability on the ground. So that's an important distinction to the previous assessments So not only do we have a more realistic picture of what may happen by understanding sort of the true Causes of vulnerability We can offer a lot more information to managers as to where they can intervene What they can do to prepare and how to reduce that Vulnerability and increase resilience In short while the efforts to reduce emissions have to continue to avoid the worst of climate change Managers can do a lot on the ground already now starting this moment To reduce their vulnerability so that those impacts will not be as severe And that leads me then to the third innovation, which is all about adaptation What you find quite apparent in our changing climate 2012 Compared to previous summaries is that there is a very big shift in tone Previously we always were able to say well, we will have to figure out what to do to adapt This time we actually looked at that we actually started to do science about adaptation What can we do? What are communities already doing? How much would that cost? If they have problems doing that right now hurdles that they might have to get over What can we do to help them overcome those barriers so they can prepare for the future The third assessment in this way offers very important new insights into what managers and policy makers can do to prepare for And reduce the risk from climate change And because climate change is already as we heard before unfolding as we speak in the state right now These efforts and adaptation are just as urgent and important as mitigation Let me close my brief remarks here by saying thank you to the state of california for continuing to support scientific research into climate change It is exciting to a scientist quite frankly To do cutting-edge work, but at the same time also be useful to people who need this information And it's my personal belief working with local state and federal agency folks that people who need to figure out What what to do to make sure that california continues to be a safe and prosperous place to be They're actually grateful that they have a reliable source ongoing source of scientific information Then just make blind guesses and and speculations about a future that is uncertain for sure But that is very rapidly unfolding in front of us. So thank you very much And with that we conclude our news conference The participants have graciously agreed to be available for someone on ones And I think you all know how to go about that. Thank you


Suppose f of x goes to infinity as x goes to infinity. Then, on the graph of y equals f of x, remember, equals means replaceable, then y goes to infinity. But, as x goes to infinity, we move right on the graph of y equals f of x, and as y goes to infinity, we move upward on the graph of y equals f of x. So, if f of x goes to infinity as x goes to infinity, following the graph of y equals f of x will require us to move right and upward. Similarly, if f of x goes to negative infinity as x goes to infinity, following the graph requires moving right and downward. And the end behavior as x goes to minus infinity describes how to follow the graph to the left. For example, suppose that as x goes to infinity, f of x goes to infinity, and as x goes to minus infinity, f of x goes to infinity, we can use those to sketch the graph of y equals f of x. What's important to remember here is that what happens near the origin is irrelevant for end behavior. And so, with the given information, anything could happen near the origin, so we'll ignore what goes on there. As x goes to infinity, f of x goes to infinity, so following the graph requires moving right and upward, and as x goes to minus infinity, f of x goes to infinity, so following the graph requires moving left and upward. Or we could try to identify a graph like 27x cubed minus 5,000x squared plus 800x, and we can do that by checking end behavior. So, remember, only the highest power term matters for checking end behavior, and so that highest power term is 27x cubed. As x goes to infinity, x cubed goes to infinity, 27x cubed goes to infinity, and y goes to infinity, so following the graph requires moving right and upward, which means our graph can't be either of these two, and so we'll eliminate them from consideration. In the other direction, as x goes to minus infinity, x cubed goes to minus infinity, 27x cubed goes to minus infinity, and so y goes to minus infinity. So in this case, following the graph requires moving left and downward, and this means that it can't be this graph, and it must be this graph.
