00:00:00.040 --> 00:00:02.220 A:middle L:90%
work done by the force pills. I want to
2
00:00:02.220 --> 00:00:08.369 A:middle L:90%
compute this and ah, that is done by computing
3
00:00:08.369 --> 00:00:13.080 A:middle L:90%
. If off our tea which access replaced by T
4
00:00:13.080 --> 00:00:18.289 A:middle L:90%
minus I Inti why is replaced by one minus co
5
00:00:18.289 --> 00:00:23.660 A:middle L:90%
sign t saw three minus co sign and the R
6
00:00:23.660 --> 00:00:30.309 A:middle L:90%
pry off T is one minus co sign t ah
7
00:00:30.320 --> 00:00:35.149 A:middle L:90%
, sci fi. So they're thought products or the
8
00:00:35.149 --> 00:00:37.950 A:middle L:90%
integral becomes in a goatee from zero to two pi
9
00:00:38.670 --> 00:00:43.240 A:middle L:90%
and there's that product So that product should be t
10
00:00:43.250 --> 00:00:50.950 A:middle L:90%
minus tico sai inti minus sign t close Scientific society
11
00:00:53.539 --> 00:00:58.560 A:middle L:90%
plus three society minus scientific society. So we just
12
00:00:58.560 --> 00:01:03.540 A:middle L:90%
cross out this term So this one zero to two
13
00:01:03.549 --> 00:01:11.079 A:middle L:90%
pi t minus he cause I he plus two side
14
00:01:11.280 --> 00:01:26.349 A:middle L:90%
Did he this home So maybe we'll have to do
15
00:01:26.349 --> 00:01:33.650 A:middle L:90%
a little bit integration by part here. So in
16
00:01:33.650 --> 00:01:38.349 A:middle L:90%
the growth Pecos I Inti, is you a sad
17
00:01:38.349 --> 00:01:44.049 A:middle L:90%
issue this TV So you times you would just be
18
00:01:44.739 --> 00:01:53.519 A:middle L:90%
sign He minus the to you is just one one
19
00:01:53.519 --> 00:02:00.873 A:middle L:90%
dt so t sign t minus koh sai nt So
20
00:02:00.873 --> 00:02:05.893 A:middle L:90%
here the entire derivative on the the entire derivative here
21
00:02:07.082 --> 00:02:13.682 A:middle L:90%
should be t square over too, minus thiss minus
22
00:02:13.693 --> 00:02:20.032 A:middle L:90%
T sai Inti plus Co sign T and the entire
23
00:02:20.073 --> 00:02:28.943 A:middle L:90%
reviews Negative too Cose I t so this one cans
24
00:02:28.943 --> 00:02:32.943 A:middle L:90%
are becomes minus sign minus koh sai nt probably to
25
00:02:32.943 --> 00:02:38.263 A:middle L:90%
pylea four pi square over too We get to Pi
26
00:02:38.263 --> 00:02:46.443 A:middle L:90%
square minus to pie Scientific I zero So we'll have
27
00:02:46.443 --> 00:02:50.772 A:middle L:90%
the worry about this time and ah co sign to
28
00:02:50.772 --> 00:02:53.992 A:middle L:90%
pie This is the same as cousins who just want
29
00:02:54.983 --> 00:03:00.073 A:middle L:90%
and the miners If you probably zero well zero here
30
00:03:00.242 --> 00:03:06.793 A:middle L:90%
zero here cause I know this one so minus one
31
00:03:14.082 --> 00:03:21.643 A:middle L:90%
so minus should be minus next before So here we
32
00:03:21.643 --> 00:03:23.763 A:middle L:90%
have a problem to pi We got this minus republic
33
00:03:23.763 --> 00:03:28.293 A:middle L:90%
Probably zero We've got an active one So here we
34
00:03:28.293 --> 00:03:34.992 A:middle L:90%
got two Pi square minus one plus one so
