So why go through all this trouble of inventing calculus? Historically, calculus was created to solve three problems. First, given a region to find the area of the region. Next, given a function to find the greatest or least values of the function over an interval. And third, given a curve, find a line tangent to the curve at a given point. Now it turns out the first problem is actually the easiest problem and was in fact the first calculus problem solved. But for a variety of reasons, we actually begin by trying to solve the third problem. So let's take a look at that one. Now before we try to find the tangent line, let's take a look at what's called the secant line. A secant line is a line that cuts secare in Latin through two points on a curve. Since we know how to write the equation of a line given two points, we can always write the equation of the secant line. For example, let's consider the curve y equals x squared plus 3x minus 7, and we'll find a secant line through the point on the curve where x is equal to 1. So first, we need two points to write the equation of a line, and x equals 1 is a half point. We need the y value to make it a full point. Well, we have a formula that tells us what our y value is, so we'll find our y value when x is equal to 1, which will turn out to be negative 3, and so our line is going to go through the point x equals 1, y equals negative 3, and we need a second point on the secant line. Now as the problem is stated, we can use any point at all. So we'll take x equals 0 as our second half point, and our y-coordinate will be negative 7, and so the second point on our secant line is going to be 0, negative 7. And now we have two points, and we need to write the equation of the line through these two points. Now the easiest way of writing the equation of a line is to know a point on the line and the slope of the line, in which case the equation of the line through the point x0, y0, and the slope m is y equals m x minus x0 plus y0. This requires us to find the slope, so remember that the slope of the line through two points is given by the difference in the y values divided by the difference in the x values. So we have two points on the line, so we'll find the slope between those two points, and now we have the slope at a point on the line, and we can use either point to write the equation of the line. However, it's conventional to use the point that we're given, so here we're told to find the secant line through the point on the curve where x equals 1, so we'll use the point 1, negative 3, and the slope of 4 to write the equation of this line. So how do we solve this problem of, given a curve, find a line tangent to the curve at a given point? To find the equation of the tangent line to a curve y equals f of x, we're going to need two things. First, we'll need a point a f of a on the curve. This is our point of tangency, and the other thing we'll need is the slope of the tangent line. Once we have these two things, we can write down the equation of the tangent line. So how do we get them? Well, let's go back to our secant line. If I take the second point of the secant line close to the point of tangency, then it appears that the slope of the secant line will approximate the slope of the tangent line. And this suggests the following approach. First, I'll find a second point on the curve that's close to the point of tangency. I'll find the slope of the secant line between those two points, and then I'll find the limit of the slope as the second point approaches the first. And this is where the calculus comes in. So let's say I want to find the equation of the tangent line to y equals x squared plus 2x minus 4 at x equals 3. So first, we should find the point of tangency. At x equals 3, y equals 11, so the point of tangency is 3, 11. We'll let our second point be at x equals b. Then y is equal to b squared plus 2b minus 4, and our second point will be b b squared plus 2b minus 4. And now I have two points, so I can write the formula for the slope between those two points. And as the second point approaches 3, 11, the slope of the secant line will approximate the slope of the tangent line. And so the slope of the tangent line will be the limit as b approaches 3 of this expression. And to find the limit, we note that at b equals 3, numerator and denominator are both equal to 0, so both of them will have a factor of b minus 3. We can find the other factor easily, and then simplifying our expression, we find the limit, which will be 8. And so we know the slope of the tangent line, 8. We know the point of tangency, 3, 11, and so we can write down our equation. Now the primary difficulty with finding the slope of the tangent line this way is that evaluating this limit requires us to factor an expression that can become fairly complicated. So to simplify the algebra, we can let our two points be a f of a, the actual point of tangency, and some point that's close by. And one way we can express a point that's close by is to let our x value be a and a little bit more. It'll be at a plus h, and our y value will be f of a plus h, and that'll be our second point on the curve. Then the slope of the secant line will be, and as the second point gets closer to the point of tangency, the slope of the secant line becomes closer to the slope of the tangent line. And so the limit of the slope of the secant line will be the slope of the tangent line. And we might ask ourselves, self, where have we seen this limit before? And in fact, this is the very limit that defines the derivative. And so this leads to an important connection between algebra and geometry. The derivative is an algebraic expression. It's a formula. Meanwhile, slope is a geometric idea, and the important connection to remember is that the derivative is the slope of the line tangent to the curve. If you learn nothing else in a calculus course, you'll probably fail the course. But among the things you should learn in a calculus course is this key concept, the derivative is the slope of the line tangent to the curve.


Welcome back to our lecture series, Math 1220, Calculus II for students at Southern Utah University. As usual, I'm your professor today, Dr. Andrew Missildine. Lecture 7 in our series, we're going to start talking about the concept of work. Now, you might be thinking, well, haven't we already been doing a lot of work in this class? Wouldn't you say? By the meaning of work in this context, we're referring to its interpretation in physics. That is, work is a force applied over a distance. As this section is going to involve a lot of physical terminology, it's worthwhile mention a few things for those who might not be up to date on their basic physical mechanics here. Imagine that we have an object whose location, position is given by the function s of t, which we see right here. We've used this before to refer to a position function. Given a position function, recall that the force of an object, which we typically denote with a capital F, the force of an object follows the rules of Newton's second law of motion, which tells us that the force to accelerate the object is equal to the mass of the object times the acceleration that it begins to have. Oftentimes, Newton's law of motion is thought of more in the following way, that if we take the force and divide it by area, that'll tell us how quickly the object will begin to accelerate and things like that. But of course, if we rewrite it in the following right here, if we have an object which we know it's mass and we want to accelerate it as certain acceleration, then this tells us exactly how much force is needed to do that. Now, the relationship between, of course, acceleration, a of t, to position is that, recall that acceleration is the second derivative of position, because after all velocity, which is the derivative of position, it's derivative is acceleration. So for our purposes, force is just mass times acceleration, and acceleration is the second derivative of position. Now to the idea of work. In the physical sense, work is a force applied over a distance. And so if we denote work typically with a capital W, work is going to be the product of force times distance. So the idea is if you have some horizontal distance and you have an object that you want to move it along that distance, well, you start exerting a force on that object, right? That force is going to be based upon the object and how hard you're pushing it, yada, yada, yada. That's the second law in action here. But as we exert this force, the force will transverse a distance, right? And the product of those two things gives us the work done to move that thing. Now work, unlike some of the other physical quantities we talked about, is a directionless object. This is what we refer to as a scalar quantity. There is no direction when it comes to work. The idea is if you were to push something up versus pushing it down versus, and when I say up and down, I mean like if you push it north or push it south, push it east, push it west, doesn't really matter. The work is going to be the same irrelevant of the direction. This is a difference between like position function, which if we have our x and y axes, zero. Position, like if you go three to the right, that's different than going three to the left, which we put a sign attached to it. So position, S of t here, is often what we refer to as a vector quantity, meaning that the direction does matter. We have a positive direction, we have a negative direction. This is also true for its derivative velocity, and it's also true for its derivative acceleration. And as likewise mass, mass is likewise a scalar quantity. There's no positive mass or negative mass. Going mass to the left is the same as going mass to the left, right? Right and left makes no difference there. As mass is a scalar quantity as well, force will be a vector quantity. Force does have a direction. So like with our little force diagram right here, a force going to the right is very different than a force going up or a force going down or something like that. And these forces add together by the usual laws of vector addition. We will only worry about one dimensional vector, so it's not going to make much of a difference. But for our purposes, force has a magnitude and direction, but work just has a magnitude. If you were to push your car all the way around campus in one giant circle, that would not feel like you did nothing, that the net effort is not zero because the direction doesn't sort of cancel each other out there. But with this formula in mind, there's really not a lot to some of these basic linear work type problems. So for one example, imagine we want to compute how much work is in lifting a 1.2 kilogram book off of the floor to put it on a desk that's exactly 0.7 meters high. So to calculate this, we're going to first calculate the weight of the book, which is its force due to gravity. So in that regard, by Newton's law, mass times acceleration, we have the mass of the book, which is 1.2 kilograms. And then the acceleration due to gravity is going to be 9.8 meters per second squared. That's just a constant here on planet Earth. That will give us the weight, the force of the book, which if you multiply those together, you end up with 11.76. And the units here would be kilograms by meter per second squared. That's kind of a mouthful. So instead, we refer to the standard units of force as a Newton named after Sir Isaac Newton, of course, for his work in mechanics here. So be aware that one Newton is a single kilogram by meter per second squared. So you can think of it as one force if a force is equal to one Newton, that's the force necessary to accelerate a one kilogram object by one meter per second squared. This does not give us the work. This gives us the force. This is just how heavy the book is. The work is then going to be the force, in this case, the weight multiplied by the distance. So we get 11.76 Newtons. And then we times that by the height, which was 1.7 meters. And so when you multiply those together, you end up with 8.232. The unit here would be a Newton meter. But again, to kind of simplify things, the unit that's often used here is a joule, capital J there. And there we go. If this was a scientific problem, we might need to worry about significant digits. But this is the math class, so I don't care. The work to lift your book is just going to be the weight times the distance it has to travel. And if you're working with scientific units, do make sure you use kilograms, meters, seconds, Newtons, joules as appropriate. And remember that one joule, remember, is just a single Newton meter. Now if we were to do a similar type of exercise about using the English units, like pounds and feet and things, how much work is it done in lifting a 20-pound weight six feet off the ground? Now one thing to remember when you're using these American-British units that pounds is not actually a measurement of weight. Pounds is actually, sorry, I said that wrong. Pounds is not a measurement of mass. Pounds is actually a measurement of weight. Pounds is a force. It's not a mass. This right here is a force. As such, you don't have to multiply 20 pounds by acceleration due to gravity, because the 20 pounds has it already built into it. What I'm saying is the force due to weight of this object is already 20 pounds, like so. And so if we want to do the work, which is just force times distance, then we would take the 20 pounds, which is the weight of our object here, and then we times it by the six feet that we want to lift it. And that ends up with 120. And here the unit actually is called a foot pound. And so we just put the two things together. It takes 120 foot pounds of work to lift the 20 pound weight up by six feet. And so for very simple work problems, this is all that one has to do. You calculate the force. You multiply that by the distance. And as long as force is constant along the whole journey, that's all one has to do with these work type exercises.


The base is under attack, repeat, the base is under attack.  I mean they tried their little hearts out and they're the best thing we have available, but man do they suck. Take gravity. For almost two millennia it was common knowledge that heavier objects felt faster than lighter ones. Everyone who read Aristotle knew that. It took more than one and a half thousand years for someone to actually run a proper experiment, examine the results carefully and say, Oh no, that's totally wrong. Think about that for a second. Century after century after century of smart, observant, open-minded people believed something about the universe that could be disproven relatively easily in about two seconds with a pair of weights. Not one person noticed in that entire time.  And yet, here we are, I'm talking to you on a screen over a massive network of computers. The technology in my watch alone represents an incredible mastery over the forces of nature and a really deep understanding of how it works.  How did we go from heavy things fall faster than light things to an intimate understanding of gravity and electrons and circuits and chemistry and all of this amazing technology which harnesses that knowledge to bring you this? Put simply, our brains didn't really manage it on their own. We sort of needed to develop a whole new way of thinking, one which was governed by a strict set of rules to shepherd our wayward brains and keep them from messing up our understanding of the world with their suckiness. You probably remember the scientific method from elementary school. If you were anything like me, you wondered why everyone was making such a big deal about this relatively simple flow chart that describes a process which is fairly obvious. To learn new stuff, you try something and see if it works. Duh. I mean, babies do this. Why are we spending so much time on it? Why am I making a poster board of this? It took me a long time to appreciate exactly why that particularly well-defined stepwise process was so important. It's a sort of navigational tool, a rigorous system that allows us to find our way in regions where we can't always trust what our brains are telling us, regions beyond what's obvious or self-evident, without getting ourselves lost. Just like you'd never try to navigate a desert without a compass or a GPS, researchers cling very closely to this flow chart for a good reason. It's the only reliable way that we've found to navigate ourselves to the underlying principles of our universe, to find out how it works, how to harness its power to our desired ends without our brains screwing everything up. It's designed as an algorithmic replacement for our intuition. And that's part of the problem that we face since we first developed it. You might follow your GPS to something really incredible, but if someone asks you something about how you got there, you might find it difficult to come up with a meaningful response. Well, I followed the directions. This is the intrinsic problem of science communication. Researchers are exploring the furthest boundaries of human knowledge and paying very close attention to the scientific method to be absolutely sure that their brains' biases and prejudices and preconceptions aren't going to leave them lost in the wilderness. But that whole process is substantially different from how humans are used to thinking, and is easy to forget that it's tapped into something that we don't usually have access to. Something essential is necessarily lost when moving from the realm of research to the realm of normal human thought, the realm of things like rhetoric and argument and policy. Many people are currently discussing a war on science, which probably sounds hyperbolic or inflammatory. I mean, nobody's forming picket lines with science like down with chemistry or no more physics. What's the deal? Well, there are a few obvious things that are cause for significant concern. Believing in climate science has become a badge of political affiliation. Diseases which we've had under control for decades are killing people because some parents no longer trust the robust findings of medical science. Some lobbyists are pushing for creationism, which is a theological or philosophical position, to be taught alongside evolutionary science in public schools. And the current administration in the United States has cut funding for all sorts of different research initiatives, including environmental science, climate science, and medicine. However, despite the fact that they're terrifying, these phenomena can be seen as symptoms of a more general cultural shift in attitude regarding the place of science in society. All sorts of different things are driving that shift, from the unintentional equivocation by journalists of knowledgeable researchers and crackpot theorists, to deliberate PR campaigns to undermine the credibility of scientists who advance inconvenient theories or findings, to the echo chamber effect of social media allowing people to restrict the sort of scientific information that they're exposed to. But the overall result is a general loss of trust in scientific primacy, the idea that if science conflicts with anything else, the science wins. That's important, because brains can come up with all sorts of cockamamie ideas of how the world ought to work, and if you don't value science over that wishful thinking, you can end up believing all sorts of crazy stuff. The war on science isn't about a group of people who hate technology and development, or who want to destroy all scientific inquiry, or who think that all evidence-based medicine is nonsense. Instead, it's about subtly dethroning science as the most reliable source of objectively true information about the world, painting it instead as one source, among many. Useful as a rhetorical tool when it happens to support our beliefs, but safely ignored when it doesn't. That is the most pervasive anti-scientific attitude right now, and it's not hard to understand where it comes from. It's difficult to bear in mind that scientifically obtained information is categorically different from other kinds, and shouldn't be treated the same way. For example, it can sometimes seem like researchers change their minds over and over again. In other sources of knowledge, that sort of vacillation can indicate confusion or ignorance. I mean, if your shopping buddy says that you look good in green, then that you don't look good in green, then that you look good in green again, at some point you're going to get the impression that they don't know what they're talking about. People will mistakenly use that principle to dismiss the findings of researchers. First aches were good for you, then they were bad for you, now they're good for you again. These guys must just not know anything. But remember, we're operating off the edge of the map here, with our faces buried in our GPS. Those shifting recommendations represent a complex web of data and analysis which is becoming more and more refined over time. Even if they change, they're changing to the best possible guess. Another example. Many people point to instances of scientists being flat out wrong, or contradicting each other, as evidence that science is just as valuable as anything else. After all, there are some published studies suggesting that vaccines might be harmful, or that the global climate isn't changing. If you have some pluses and some minuses, then surely we can just pick and choose the studies that allow us to believe whatever we like, right? Well, no. The inductive statistical nature of science is an inherent part of its operation, and researchers are all too aware that even diligent experimentation can sometimes produce anomalous results. That's why those results are always given as a probability. There's always a very slight chance that something weird happened while they were recording data. But again, the balance of that data is still the most accurate picture that we have. We actually expect it to be wrong a small percentage of the time, but that doesn't imply that the entire gross body of data should be ignored. Now, I'm not going to argue for scientism, the idea that science has all the answers. I think that there are definitely areas which no amount of carefully collected data will tell us what to believe or how to feel. It's also true that some people deliberately publish incorrect or misleading information in a vaguely science-y format, and that scientific consensus has been wrong, even very wrong in the past. However, I will argue this. For any question about the world and how it works, it is always better to trust a scientific conclusion than whatever this comes up with. Most people won't claim that they oppose that position, but they will suggest that scientists just don't know for sure yet when scientific findings conflict with their desired beliefs. If you see a meta-analysis which demonstrates that spanking is an ineffective disciplinary measure and think to yourself, eh, they just must not have controlled for something. That's the war on science. If you read the NIH's Dietary Recommendations and think to yourself, yeah, but my grade on T8 like that and she died at 55 of cancer, that's the war on science. Those attitudes are unilaterally corrosive to scientific primacy, and while their short-term effects can just be frustrating, their long-term effects might be disastrous, as our near future is going to depend a whole lot on those researchers and their navigational tools to lead the way. We can either rely on this system with a proven track record and the knowledge that we gain with it to steer and predict and inform that future, or we can just try to wing it the way that we did for millennia, you know, like with gravity. How can we convince people that science holds a privileged position over other sources of information? Are you going to march for science on Saturday, April 22nd? Please leave a comment below and let me know what you think. Thank you very much for watching. Don't forget to follow us, subscribe, blah, share, and don't stop thunking.


Majesty. Majesty. Majesty. I'm going to see you again. So will I. It's been too long. Too long between. Right. We'll get press waves coming through. Hi. Hi. Good. Good. How's the family? Just fine. Dispects. Right. So you may be finding a new job soon. Another appointment. Who are you? Who are you?  I'm the captain. You have been given a great deal of misinformation. When he says. No one's risen to our defense lately. No one's risen to our defense from here lately. Well that's just a burst in the last couple of days. Flights. Do you think that you will send her to an investigatory position or something like that in the near future? As I said, there's no further answer than it is today. I would only suggest I know I can't shut off the leaks. But you ought to be more astute at recognizing whether the leaks are true or not. Has anyone recommended, like Mr. Regan for example, that you consider it a position for her? No more comments on that. About the visit of His Majesty. Are you satisfied with his address at the United Nations? Especially when you said we are prepared. Does that mean Jordan and Thielo and the Arab world or what? We're going to be discussing all those matters here together. Okay. Thank you. Exit to your left. Quickly. Is that it? No, no. Is this the second? No. We were supposed to be blown away with the hurricane. Yes. The change in the morning started. We thought it was going to happen. And by early afternoon it was just like this. It was the same in New York, unfortunately. So we were again wondering what was actually going to happen. But it passed very quickly. And fortunately the time it has been. Like to play. To say that, I believe we have come a long way.  My feeling that you are so interested in making a great contribution towards resolving these problems and securing peace and justice and dignity and a chance for all the people in our area. We have tried our very best to give it. And I have come a very, very long way so far. We are almost, I won't say at the end, but at the beginning. And it all looks extremely promising. But we need your help. And the help of our friends. And we have made some very important and useful talks in the last few days. So this was kind enough to listen to us. And meeting the first night arrived. Someone gave me the answer. And I decided the cabinet room was the best place for it. And it seems it's a decision machine. And when it gets down to everything that's failed. It's grand. We'll leave it on yes. We know it's on yes. Well, we, I know that first of all, I'd like to thank you to the nation for the cooperation and joining in our military exercises. Bright storms that made us marks kind of the first in our relationship with all the other property things that we've done. And we've been pleased to, you know, to notify the Congress as we said we would about the arms package. And we're making the maximum effort. But it won't be easy. We're determined to win. And now I know that you're going to see congressional leaders. And that's an excellent idea. And you are the best spokesman for peace. And you can perhaps do a good deal to help us in this second-depth cooperation in Congress as we go forward in this. I have just had a very productive meeting with King Hussein of Jordan. Jordan has been moving steadily and courageously forward in the search for a peaceful negotiated settlement of the conflict in the Middle East. And Jordan has not wavered from this course despite terrorist attacks against its diplomats and its interests abroad and the threat of worst to come. I told His Majesty in May that he could count on us for the economic and security assistance Jordan would need to address the risk that it is taking. Indeed, over the summer the Congress improved an important package of economic aid for Jordan. But on Friday, I notified the Congress that I would now be proposing a package of defensive arms. And these arms are important in meeting Jordan's proven defense needs and as evidence that those who seek peace will not be left at the mercy of those who oppose it. But peace, not arms, has been the focus of our discussions with our Jordanian friends. And all of us, Jordan, the United States, and Israel, share the same realistic objective, direct negotiations under appropriate auspices before the end of this year. There are complex and sensitive issues which must be resolved before actual negotiations can begin. But I believe these issues can be resolved. Let me repeat that the United States is dedicated to achieving a just and durable peace between Israel and all its Arab neighbors. We'll do all that we can to maintain the momentum already achieved, much of it, the result of King Hussein's personal courage and vision. The goal is peace and stability for Jordan, Israel, and all states in the Middle East. The way to that goal is through direct negotiations on the basis of UN Security Council Resolutions 242 and 338. The time to begin is now. I know that His Majesty shares this aim, and I am proud to work with Him in this noble endeavor of peace. Your Majesty, once again, you have my thanks and the thanks of all our people. I wish to thank my dear and great friend, President Reagan, for his kind words. I value his friendship and the long-standing relations which happily exist between our two countries and which are based on our joint commitment to the common values and principles of liberty, freedom, equality, and human rights. I have had a very useful meeting with the President. Our discussions were as frank and honest as our friendship dictates. I have reiterated to him Jordan's commitment to a negotiated settlement of the Arab-Israeli conflict within the context of an international conference to implement Security Council Resolution 242. I have repeated to the President what I stated in my address to the United Nations three days ago, namely Jordan's unwavering position in condemnation of terrorism irrespective of its nature and source. Jordan condemns violence and is committed to a peaceful resolution of the Arab-Israeli conflict. We are prepared to join all parties in pursuing a negotiated settlement in an environment free of belligerent and hostile acts. I have also expressed Jordan's satisfaction with the positive development of our bilateral relations, especially in the economic and military fields. We endeavor to strengthen our ties and hope to continue our close cooperation in all areas. I wish you, Mr. President, continued good health, happiness and success. And may the Almighty God bless you and grant you strength to lead this bastion of democracy to ever greater heights. Thank you, sir.


Hey, Bola buddies. Thanks for watching. Okay. This is a What did the goodwill on eBay sell so eBay? Let me say that again Goodwill sells on eBay so I found a store and I'm gonna show you some big money bolos that they sold so what this store does it seems to focus on certain Categories and we're gonna talk about that But I'm guessing that maybe the local stores mail these items to this location Or I don't really know how it works But these are some big money bolos that never hit the goodwill store floors and they go to eBay to be auctioned off Now one thing really cool is that they start all of their auctions at nine dollars and ninety nine cents so this may be a store that would be good to bookmark or What do you call it mark as a favorite and check it periodically because you might be able to snag a good deal They do a lot of bundling So could be good for resellers. So let's look at their big money bolos and this is gonna help us learn and I Can't I mean everything was donated. So we're just gonna talk about it We're gonna see what I pulled up some of the unexpected ones and we're just gonna go through each tab and We'll move quickly and talk about them. All right But again, I will try to remember to link it down in the description so that you guys can bookmark it All right, so the first item that sold The first item that sold okay, so this store has so much glass baby in it I don't know if every goodwill in the world is like sending this store their glass baby or what but This store definitely knows about glass baby being a bolo and I actually did a little bit of research on this And it's a pretty cool story. You guys should definitely Google it But from what I understand this is actually hand blown glass. So pretty pretty cool now. I what I Have figured out just from looking at comps on glass baby is that the color combinations Determine the price now this one sold for one thousand five hundred and twenty five dollars and ninety two cents It's called feeling groovy and it's orange So if you go into the bid history here 18 people were bidding on this 18 unique bidders so that tells me that this is a rare hard to find item if there were 18 different people bidding on it With 38 beds the winning bidder had 141 feedback. So if that was zero feedback, you know Yeah, I might be concerned. I don't know who knows if it got paid for there is one way that we can look and If you go into the feedback and you type in glass baby It will pull up all of the feedback now the problem with this is that not everybody leaves feedback I don't know why this is taking so long Okay Oops, there seems to be a problem. Well, we'll try one more time feedback Okay, so I Typed in glass baby to the feedback and you can see right here. These are the people that have left Feedback here's one that went for six hundred and thirty This particular one they may not have left feedback for but you can see all the different prices and it definitely ranges from Small amounts to big money.
