This video were asked to reversible over Steve Extra Light minus y X is equipped next one way to my next one worth see as the line segment connecting X one y one to extradite. So, first of all, with a for amateurs display So we're going to subtract extra my 61 and why to minus Why one when we get our gaze in her are you gonna be? And we know that X is x one plus a B and bodies by one bt so excess extra horse bt and vines. Why one horse beauty services That's what uh so X is a time Steve's or a is extra bling. That's what and why is why one plus R B. I'm just on our t varies from 0 to 1. So if your partner zero for tea, you're gonna get X one y one, which is your first point, and you you plug in 1 40 you're going to get next to Los X 2.6 just next to and why is he put the next one plus extra Linus? Sorry. Why why is he But why? I love plus y tu minus one. I just want to So we get next to come off like So this is our perimeter organization. So now we're gonna change the integral so you can change this integral right here. All in terms of So we're going to We're gonna We're gonna try to take me to go over perspective. So first we have the integral from 0 to 1 on our exes exploit Plus expired next to mine. Sex won t on our he wise. Just a derivative off. Why would respected t Just just want to remind us why I wanted to You minus now are why is why one last point to a minus Bi won t times DX, which is just still buying sex works. But I weeks bad So we have X one times like two lines. Why one plus extreme wings for one for times like to minus 41 times T minus one times extra one sex one minus one to minus five extra money sex 70 on all that. So this might look a bit tricky, but it's pretty straightforward. You're just distributed that we noticed that this this are equal so we can still against hero and then we're gonna distribute are explored. We're going to distribute. So we get back sometimes. Like to buy this. Excellent. So I want minus y one times, X two plus by one time sex for here again, we notice that we can cancel our X one y one. So we're left with being truthful from Syria. One of X one times one to minus six to minus 41. The teeth. And since we have no t here, we've been uncovered as a constant and the integral of the cheese. Just to you. S t goes 101 So you have excellent times. Like to my sex, dear line, the extra times for everyone and one linings. Here's just for him, sir. Now we proved what we wanted to show that integral it's equal to X one. Why? To my business too. She's exactly this is exactly what I wanted to show. Only just did. All right. Great. So far number report be They're telling us in general, we want to show that the area this report true 1/2 x one times right. Two lanes 62 times one suspects three times life or a minus Uh uh X three times by two. And but what stopped the doctor? Plus excellent backs renderings One times Laurean Mining sex in terms right in this one so over and have to prove that person you know is that the area beginnings half the close in a row for the integral of X t y minus. And for a general point that state starts the next morning goes to x. Sorry x I Why I enclosed to expire plus one y plus one. But we want a first fewest. Her amateurs. So the thing is, you take x I plus one minus x side. That's why I plus one minus y I said, This is are a of the and we know that back says X one horse painting and white one plus beat so are excellent is just excited about a expect plus one minus X. I we want to play that by I know why it's right one. Just why I plus why I lost board, find this white guy Times and t goes from zero to okay. Now you need to determine the extent deities with Texas just excited. What's one less exciting? Andi lies just why I plus one minus y And now again, just like importante We cook air for things back into musical on We just break from zero and I'm after break Distribute. You noticed that we can do some cancellations. You can see this with this. And then all what we're left with is and and then we're simply been there the first term and the third term district. So we have 1/2 on the outside, Mrs. One formula for area ventured Muslims a little one. No backside like I post one minus exciting by I minus Y I x nine Force one Plus Why I times excited again. You can cancel. That's with this. So I just left with 1/2 times in to go from 0 to 1 of Rex started y plus one minus x I plus born. Why I And then since these are all X's and y's and don't contain to use, we can force them to the outside and the integral DTs just cheese was 1/2 excited. Why? I posed by an expects are one by all right, and then t as it goes from 1 to 8 from 0 to 1. What? This is just one minus zero Or just so now we get that the area is 1/2 excited. Why? I close one in this ex cycles. One point then, if we want to find the total area or what we do is reach some from I through end minus one 1/2 excited. Why bust one minus X I plus one? Why I and then we get what we wanted to show. But there's despite made a little bakery in here, so it should be X ready. Why now that now we proved what we wanted to show and now for part, really have to do is we have a Pentagon to determine the area from the former lovers Start. We found a part dean and were given 12345 coordinates and just slave about explode y one x 212313 Forward for expert for five. And then now you're gonna put these into the formula of returning in Part seven for feeding Germans before and now it's just straight up again. Chuck, there's nothing more. So we have 1/2 times zero minus zero times weren't buying. Sierra Times two plus two times three minus one times one plus one minus two zero minus three 10 times one, uh, lying us the negative one times two. So basically what we can formula right here, right here and then for end. We just put it five. So that's that's That's our value for Ed. And then when we plug in the values relabel the except Flex X is in the lives what we get. And nine, perhaps 4.5.
