00:00:00.280 --> 00:00:05.469 A:middle L:90%
Let's start off by just expanding this into Grand X
2
00:00:05.469 --> 00:00:15.359 A:middle L:90%
Square to Excite X Science, where then we could
3
00:00:15.359 --> 00:00:18.350 A:middle L:90%
go ahead and split this sense of three generals.
4
00:00:21.739 --> 00:00:30.510 A:middle L:90%
Oops, think of the ex first and then in
5
00:00:30.510 --> 00:00:35.909 A:middle L:90%
a gruel of science squares. So for the first
6
00:00:35.909 --> 00:00:41.880 A:middle L:90%
one, just use the power room here. Let's
7
00:00:41.880 --> 00:00:46.570 A:middle L:90%
use and enrich my parts. Let's take you to
8
00:00:46.570 --> 00:00:54.570 A:middle L:90%
be x two u equals the x t me signed
9
00:00:54.570 --> 00:00:58.659 A:middle L:90%
the eggs. So he is negative. Cosign x
10
00:01:00.469 --> 00:01:03.250 A:middle L:90%
sound. Recall the formula to be replaced the integral
11
00:01:03.260 --> 00:01:07.379 A:middle L:90%
with UV minus in rule be, do you?
12
00:01:07.780 --> 00:01:11.510 A:middle L:90%
So we have plus and then two times. So
13
00:01:11.510 --> 00:01:15.849 A:middle L:90%
now we do you times V So this times this
14
00:01:15.439 --> 00:01:21.599 A:middle L:90%
that's negative. X co sign X and then minus
15
00:01:21.599 --> 00:01:25.239 A:middle L:90%
in a rule z Do you? So I have
16
00:01:25.239 --> 00:01:26.150 A:middle L:90%
a negative co sign. Let me just go ahead
17
00:01:26.150 --> 00:01:34.719 A:middle L:90%
and cancel those minuses. And then finally, for
18
00:01:34.719 --> 00:01:37.239 A:middle L:90%
the last integral. It's used a half angle formula
19
00:01:37.239 --> 00:01:42.909 A:middle L:90%
for sign, so it's one minus co sign to
20
00:01:42.909 --> 00:01:49.030 A:middle L:90%
X, and we pulled out the two. So
21
00:01:49.030 --> 00:01:57.799 A:middle L:90%
let's simplify this integral of co sign a sign.
22
00:01:57.439 --> 00:02:02.049 A:middle L:90%
Don't forget the two out here. So here,
23
00:02:02.049 --> 00:02:05.829 A:middle L:90%
in a goal of one X. Don't forget the
24
00:02:05.829 --> 00:02:07.979 A:middle L:90%
one half hour in the front, out and then
25
00:02:07.979 --> 00:02:12.490 A:middle L:90%
the end. Roll over here that'LL be a minus
26
00:02:12.740 --> 00:02:15.379 A:middle L:90%
sign, too. It's over, too. But
27
00:02:15.379 --> 00:02:16.349 A:middle L:90%
then we have another two over here. So as
28
00:02:16.349 --> 00:02:23.000 A:middle L:90%
a four plus our constant of integration, see?
29
00:02:23.900 --> 00:02:24.030 A:middle L:90%
And that's your final answer.
