00:00:01.909 --> 00:00:04.870 A:middle L:90%
Okay, so I'm going to explain the setup of
2
00:00:05.049 --> 00:00:08.740 A:middle L:90%
this problem. So I'm not completely sure. Author
3
00:00:08.750 --> 00:00:12.529 A:middle L:90%
, house author, design department Who is solvable?
4
00:00:12.539 --> 00:00:15.330 A:middle L:90%
I think I'll stop. It's the cinema and explain
5
00:00:15.410 --> 00:00:20.879 A:middle L:90%
why First of all that the way to this kind
6
00:00:20.879 --> 00:00:22.530 A:middle L:90%
of blind, The whole part of the first things
7
00:00:22.530 --> 00:00:26.120 A:middle L:90%
to fill out Yes. So we computed derivative with
8
00:00:26.120 --> 00:00:30.649 A:middle L:90%
respect to tee off home Finish off that Megan he
9
00:00:30.660 --> 00:00:38.740 A:middle L:90%
appealed by for that group Chairul Thank you. Yes
10
00:00:39.439 --> 00:00:42.710 A:middle L:90%
. We'Ll be at this after you simply for using
11
00:00:42.710 --> 00:00:45.350 A:middle L:90%
the fact that Science Corp Roscoe's and spirits What?
12
00:00:46.119 --> 00:00:53.390 A:middle L:90%
You get this And, uh so that's trying to
13
00:00:53.399 --> 00:00:56.229 A:middle L:90%
figure out what was it A crow is We tried
14
00:00:56.229 --> 00:01:03.399 A:middle L:90%
to integrate from zero to two parts. Ask you
15
00:01:03.409 --> 00:01:06.959 A:middle L:90%
so is heat with a negative three t Oh,
16
00:01:06.959 --> 00:01:14.030 A:middle L:90%
Sy Q forty. Why square it'll negative to Teesside
17
00:01:14.030 --> 00:01:25.349 A:middle L:90%
Square forty z The s is three squared off too
18
00:01:29.420 --> 00:01:37.250 A:middle L:90%
Not funny e t So we have everything set up
19
00:01:38.040 --> 00:01:42.079 A:middle L:90%
zero to two pi We put three squared off to
20
00:01:42.079 --> 00:01:44.250 A:middle L:90%
you for months and we have each with a nephew
21
00:01:44.250 --> 00:01:51.849 A:middle L:90%
seventy coz i cube for teeth Sai square for teeth
22
00:01:52.640 --> 00:01:57.260 A:middle L:90%
Hey, so this will be a very difficult.
23
00:01:57.260 --> 00:02:00.632 A:middle L:90%
Integral to it. I don't think I'll completed because
24
00:02:00.643 --> 00:02:04.692 A:middle L:90%
I have to use our other five different pages,
25
00:02:04.692 --> 00:02:07.403 A:middle L:90%
too, to finish it. Let's give you an
26
00:02:07.403 --> 00:02:10.473 A:middle L:90%
idea how to how to deal with qualities like this
27
00:02:13.832 --> 00:02:15.432 A:middle L:90%
. Well, maybe the things you can do is
28
00:02:16.393 --> 00:02:20.913 A:middle L:90%
visit ideas in general when you're dealing with trigonometry,
29
00:02:20.923 --> 00:02:23.543 A:middle L:90%
integral high power are usually harder is with the always
30
00:02:25.043 --> 00:02:29.733 A:middle L:90%
They're larger and goes, So the idea is you
31
00:02:29.733 --> 00:02:32.312 A:middle L:90%
use product to some former to to to write the
32
00:02:32.312 --> 00:02:36.552 A:middle L:90%
product of true gumption function into the sun and,
33
00:02:36.552 --> 00:02:39.413 A:middle L:90%
as you know it shop the exponential function times trigonometry
34
00:02:39.423 --> 00:02:45.152 A:middle L:90%
function without the power is some power in your manage
35
00:02:45.152 --> 00:02:47.293 A:middle L:90%
both to Dubai. Use the integration by parts they're
36
00:02:47.293 --> 00:02:51.603 A:middle L:90%
being say, still very lengthy process so I can
37
00:02:51.612 --> 00:02:53.483 A:middle L:90%
try to show you how to deal with is the
38
00:02:53.483 --> 00:03:00.832 A:middle L:90%
first step. For example, co sign square forty
39
00:03:00.842 --> 00:03:08.143 A:middle L:90%
size square forty. This will be one over to
40
00:03:08.143 --> 00:03:17.103 A:middle L:90%
sigh eighty square. So one over for size square
41
00:03:17.112 --> 00:03:29.962 A:middle L:90%
eighty, this will be one over eight minus one
42
00:03:29.962 --> 00:03:37.793 A:middle L:90%
over eight. Co sign sixteen t. Yeah,
43
00:03:39.633 --> 00:03:43.643 A:middle L:90%
and, uh, but that's not everything we have
44
00:03:43.652 --> 00:03:45.682 A:middle L:90%
. We have coast. We have another co sign
45
00:03:45.682 --> 00:03:47.272 A:middle L:90%
. Fourth he So we have. So this part's
46
00:03:47.272 --> 00:03:53.043 A:middle L:90%
everything I'm writing. Red should be one over eight
47
00:03:53.332 --> 00:04:00.574 A:middle L:90%
forty minus one over eight. Co signed sixteen p
48
00:04:02.234 --> 00:04:08.403 A:middle L:90%
. Coz I'm forty here. We have to use
49
00:04:08.413 --> 00:04:16.593 A:middle L:90%
another product of some form lock in. So coz
50
00:04:16.593 --> 00:04:23.903 A:middle L:90%
I off our coast on beta is, uh is
51
00:04:23.913 --> 00:04:30.874 A:middle L:90%
co sign off a plus, baby, Huh?
52
00:04:30.463 --> 00:04:36.574 A:middle L:90%
Minus coz I off minus pate are over two.
53
00:04:38.223 --> 00:04:46.884 A:middle L:90%
We have to divide this. Those are here,
54
00:04:46.884 --> 00:04:55.324 A:middle L:90%
I think is plus no anyway. And did you
55
00:04:55.324 --> 00:04:58.514 A:middle L:90%
hear? So anyway, we covered it into this
56
00:04:58.514 --> 00:05:01.514 A:middle L:90%
and it's off them. We can do the each
57
00:05:01.514 --> 00:05:05.824 A:middle L:90%
of them, like, eat like that If eighty
58
00:05:05.834 --> 00:05:12.733 A:middle L:90%
co sign Bt this all each of them is the
59
00:05:12.733 --> 00:05:15.463 A:middle L:90%
standard power in your congress too. Where you do
60
00:05:15.463 --> 00:05:18.303 A:middle L:90%
the introversion by part and do the rearrangement to you'LL
61
00:05:18.303 --> 00:05:23.704 A:middle L:90%
be able to, uh, together value off this
62
00:05:23.704 --> 00:05:25.723 A:middle L:90%
integral and as you and you have the pocket in
63
00:05:25.723 --> 00:05:28.254 A:middle L:90%
here which I think is way too long for the
64
00:05:28.254 --> 00:05:31.463 A:middle L:90%
purpose ofthe one video. But I hope I hope
65
00:05:31.463 --> 00:05:34.644 A:middle L:90%
this this explains the concepts. And if you want
66
00:05:34.644 --> 00:05:38.463 A:middle L:90%
to go on and on, figure out the detail
67
00:05:38.463 --> 00:05:42.103 A:middle L:90%
you can You can't do it yourself. Or if
68
00:05:42.103 --> 00:05:45.314 A:middle L:90%
you want to just know the approximate value you can
69
00:05:45.324 --> 00:05:47.403 A:middle L:90%
use a computer to compute this
