Okay, Hello, I'm here to teach you how to apply that training metric. To watch a short video, a little recap about the definition. These functions we have seen before. This is the side opposite. This is our sequence formula of this sine function. Sine theta equals opposite divided by the hypotenuse. We don't write simple sine function. Sine of theta is theta I and II. Sine of theta equals the ratio of the length of that hypotenuse. Adjacent hypotenuse. Plug-in wanted function is tangent function. As I said before. These sounds very fancy. Very simple. Tangent of Theta is Theta equals the ratio of the length of the side opposite theta. Which is a decent work. And judge, sounds familiar. I just went blank. That's correct. You don't see anybody want to scan in one of your videos? Just review what we just did. Heat up. By kind of alternate gca, hypogynous and opposite bitmojis made with D. Alright, so now we're going to do a quick intro to predict antibiotic based on the definitions of the trig functions. So here you go. Acronym. So because Alba has anyone ever before? Yeah. Okay, Perfect. So what do you already do this in another way? What does a unique way to remember? So we tell them. So if you take out your laptops, I did grade and the right to access the jaguar and we find that these are the slides are already. Once you're finished, please upload your denied to the gym heart. Also, your ingredient. In about 4 min. We'll go slow. Does everyone know what an markets? Like? Every good. Yeah. You're right. Thanks. All right. There we go. Awesome. Name on there, sticking out on anything. One more time. I said is you're solving. What group is that? Just put your name on them or whoever it is. Your attention up here at meet till you have your gamer. Sarah owns her car and three other. Very nice. The kapha, snakes on horses captain has told during Apple's fault, create a healthy habit. Now, it's not coherent. Something orange has political art or art or chiropractic appointments, had to open ankles. Okay, so now that we form over here with the trig functions are going to focus on three trig functions that realistic scenarios. More places that there were things we're going to focus on. Okay, so the first question that we wanted to look at is how do we know when to use each shirt electric. So we're going to look at how we decided we needed sine and cosine. Let's start with this example. So we have triangle ABC and we're given, we have angle a is 60 degrees. Ac. Side AB is our unknown side. So what we need to use your side AB, be the opposite side. You already have an adjacent side, right? Right. What about AC? Right? Now? The categorisation side and our hypotenuse shape function that relates the adjacent side, talking to groups or 10 s. And then I have my iPod. Cosine function. Cosine is defined as adjacent over hypotenuse. Look at Hollywood. Solving for our unknown side. So we have our triangle ABC where we replace our question marks that we can solve for this side. So first of all we wanna do is we want to set up our equations that we have on the left side. So our degrees, so we're gonna write cosine of 60 and on the right corner by our fraction of our adjacent over hypotenuse. So can someone tell me what fraction should be? Right? So now we have our equation set up. So we can just use algebra to solve. So we're going to multiply the thigh on both immediate five cosign of 60 equals x. And then we try to use our calculator. And you get five times one-half, which is 2.5. Library. Trying to solve these questions were first starting to look at that size. We're given, decide on our trig function and set up our equation to solve. So does anyone have any questions before we do this first worksheet activity which you can find on Canvas, or you can click on the link on the working groups on three questions. I think when you're doing these problems, make sure you identify your trig function first. Then you can set up your equations and solve it. If you need a calculator, you can just look up counseling on Google. I do first. Work. Just make sure you switch it to degrees. We aren't finished. Question. Each problem will be presented by group. So you're writing this on tape, which was overweight now and on the right to know actually, Morning. Hello, everyone. So I always like, Wait, what's going on? Hello. There's a bar on the left because it's not. My browser's 13.5. What are you guys ready? Maybe just explain to us why you chose. Yeah, Perfect. So Angular chose tangent because the opposite and adjacent side equation and solve and you should get that a equals some number. Tell us why you should assign. Because opposite over hypotenuse. So your answer should be 643 after using your calculator and one decimal 0.1 worker's number three. Again. So we did this tension opposite hypotenuse. Sorry, I looked at that. I'm sorry. Jason. So that's going to be close side, close side of 26 equals opposite over hypotenuse. The fluid over 15. 15 times cosign 4,613.4. Problems from real life situation. Alright, so now we're going to see how it functions in basketball. So we're actually going to a real life example. So I'm going to need two volunteers before they actually do the example. A visual representation on the board so you can see how we will be using the trig functions. So as we can see from the district, from Jacob, if the adjacent side, the height of a loop or out to all Beavis is the opposite. I want Jacob shoots the bullet. That will show the hypotenuse. The angle of the shot will be shown right here, would be the Fourier series. So we're going to look at problem that has to do with basketball and using the trig functions. So just take about 20:17, So just please yourselves and then we'll speed it up. Yeah. Okay. So LeBron James is trying to make a buzzer for your shot when he say 20 ft away from the base of the vesicle, the angle formed when he shoots. The ball is 63.4 degrees. How high? Off the ground incident. Okay. So first, can anyone tell me where on the triangle that angle formed and he shoots the ball is 63.4 degrees. Does anyone know? Right? Now we also know that the rod is steady 20 ft away from the base of it escalates. Anyone know, right? That would be perfect. And you know, what size calls or anyone else, you don't know. Crap. Okay. So what we're finding is says how high off the ground is. We're going to denote this as H. That's who we are, unknown variables. Anyone know where that would be on the triangle? Or a true God? How am I? Correct? Okay, so think about, I'd say a minute or so to work on your group and I will come back actually before you do so can you guys just take 20 s or so to figure out what trig function you would use this in your groups, you can discuss it. Okay, so can you guys raise your hand? Side? We get sine sine cosine tangent. And I don't know the definition of tangents and someone told me. All right, so take about 30 s of our bodies problem, then we'll go over it as a class. And you just write it down. Slow. Breathing. Raise your hand when you guys are finished and got it. Got it. Okay. So first off, we're going to do is we have ten. I said before we know that a are presented 63.4 degrees. So awesome. So before we had opposite over, adjacent and are opposite and adjacent is 20 ft. So by using these algebra, it would cost like 20 on each side. H and H equals 39.9 ft. Which track to the whole number is for everyone. Got that. Okay, So now we're gonna work on a worksheet. You can run it on Canvas are the slides that I label the sides of the angle and its odds ratio and so on. All right. Guys. Prior to that, emotional walls as she clicks F sharp motion. That's pretty easy. It's almost out of time. Yeah. What's the question asking me how I felt. You can just get some number. All right, so negative. Negative. All right. Can I get somebody come up to my triangle? I don't forgive. So resize these tangents because we have Jason wanted to do, but you're trying to follow. The question is, what's the distance between this where at least I answered the wrong thing right there. So then we have to use I want to know if there's any affording. The rest of the observed with this. What is co-sign? Like? What's the definition of adjacent over hypotenuse here? It's upside down. So then you multiply both sides by x? I don't know. I don't know. Did anybody says three is 76 to 15 divided by that? 1970. Anyone else? Yeah, that's perfect. Remember to please. Thank you. Again, you're not working in your groups. Enslaving worksheet three. So there's two pages. The first page, the first two problems and don't go on to the next page for problem three until instructed to do so because that's what we do in a cactus. Again, doing the same thing is true if I try and solve them. Once I have the world probably excuse me. Have you ever started straight up trapping for some of us as a nurse, right? Yeah, I'm sure. Okay. Wait for them to want to set it up. Let me give you one, give me their number one. Okay. Do you wanna explain coming over x? The algebra for hundreds to thousands. So did anyone get anything? All right. Good job. And then can I get a volunteer to come either answer for number ten? We got 14. You want to explain what we did because our necessity equal to seven over x. And then we eventually get to x equals seven divided by the cosine of six. X equals four. Good job. Good job. You guys can scroll to the second page. There's one more problem. This isn't any visual problems. Your own response. But make sure you put your name on it. Write your name. Why is that enough? To wrap up? When you're done, you can just apply the middle of your tables and we'll collect them at the same time. Well done. You guys want to see just like writing. Good. Sometimes they are just going to go over, reuse the software. For the entire second half of this lesson. The first one is read the problem and our problem. What should we do that? To monitor our triangle and you want to label it with our given and what is the kind of architecture? What can we do? Right? I'm going to decide or trig function. And after that, you can set up, right? And now we have our equation, our last step for you guys so much for your participation and for listening to our presentation. We hope you learned something. Oh, yeah. Why? It's really hard to get into that. All right. Good morning. Sorry. Just wondering. Yeah. The first time. Hello. Sure. Now what happens? Good morning. Sorry. I meant was that because I don't want to lead off.
