00:00:00.690 --> 00:00:02.690 A:middle L:90%
it's clear. So when you married here. So
2
00:00:02.690 --> 00:00:06.320 A:middle L:90%
we're gonna take the derivative in terms of our since
3
00:00:06.320 --> 00:00:10.970 A:middle L:90%
it's each of our for a e to the are
4
00:00:11.189 --> 00:00:17.640 A:middle L:90%
over eat the R plus B Then we take that
5
00:00:17.649 --> 00:00:23.850 A:middle L:90%
ate out get G over d r Were each the
6
00:00:23.859 --> 00:00:30.600 A:middle L:90%
r over eat the R plus B. This is
7
00:00:30.609 --> 00:00:35.049 A:middle L:90%
equal to t over de arm or eat the R
8
00:00:36.539 --> 00:00:42.609 A:middle L:90%
terms Beats the art plus B minus. Beat the
9
00:00:42.619 --> 00:00:48.109 A:middle L:90%
art d over d. R. You two are
10
00:00:48.109 --> 00:00:55.149 A:middle L:90%
plus B over eat the R plus B square.
11
00:00:59.039 --> 00:01:02.549 A:middle L:90%
Then we put a at the end and when we
12
00:01:02.549 --> 00:01:10.890 A:middle L:90%
simplify, you get a times eat are come meet
13
00:01:10.900 --> 00:01:19.700 A:middle L:90%
our plus B minus eat Our plus zero kind eats
14
00:01:19.700 --> 00:01:23.650 A:middle L:90%
the R all over each the r plus B square
15
00:01:30.040 --> 00:01:36.530 A:middle L:90%
. When we simplify yet eh be beat to the
16
00:01:36.540 --> 00:01:41.150 A:middle L:90%
r Over eat the R plus B square
