1
00:00:00.640 --> 00:00:11.210 A:middle L:90%
take the integral of both sides the integral of sine
2
00:00:11.220 --> 00:00:14.580 A:middle L:90%
as negative co sign data and a girl of coastline
3
00:00:14.589 --> 00:00:16.820 A:middle L:90%
is signed data. And remember, we must out
4
00:00:16.820 --> 00:00:20.969 A:middle L:90%
r c. Okay, now substitute end if of
5
00:00:20.969 --> 00:00:23.149 A:middle L:90%
prime zeros four, then four is negative. One
6
00:00:23.149 --> 00:00:26.350 A:middle L:90%
pus era policy there for five is our seed.
7
00:00:27.480 --> 00:00:45.250 A:middle L:90%
Therefore we have now take the derivative and we get
8
00:00:45.259 --> 00:00:48.979 A:middle L:90%
off of zero is basically the same thing again.
9
00:00:48.979 --> 00:00:51.189 A:middle L:90%
We're taking fire. We're taking the integral again.
10
00:00:54.439 --> 00:00:58.380 A:middle L:90%
Given the derivative we're taking the integral we can do
11
00:00:58.380 --> 00:01:00.750 A:middle L:90%
. Note this with Kay cause our previous constant with
12
00:01:00.750 --> 00:01:06.579 A:middle L:90%
C we're taking the interval twice. We get k
13
00:01:06.579 --> 00:01:14.950 A:middle L:90%
equals for Therefore we get off with data. It's
14
00:01:14.950 --> 00:01:19.939 A:middle L:90%
a negative sign of that, uh, minus coastline
15
00:01:19.939 --> 00:01:23.969 A:middle L:90%
did, uh, because five data plus four.
