00:00:00.640 --> 00:00:03.629 A:middle L:90%
it's close. So when you read here So for
2
00:00:03.629 --> 00:00:10.619 A:middle L:90%
part A, we have each the derivative. It
3
00:00:10.619 --> 00:00:17.570 A:middle L:90%
was equal to three times the derivative of plus eight
4
00:00:17.579 --> 00:00:24.170 A:middle L:90%
times the derivative of G. This becomes equal to
5
00:00:24.170 --> 00:00:29.359 A:middle L:90%
you. Plug in four for X and you get
6
00:00:29.370 --> 00:00:39.020 A:middle L:90%
three times six plus eight times negative three, which
7
00:00:39.020 --> 00:00:45.950 A:middle L:90%
becomes equal to negative six. Report be Each is
8
00:00:45.950 --> 00:00:50.250 A:middle L:90%
a product of F N G. So we get
9
00:00:51.039 --> 00:00:57.350 A:middle L:90%
the derivative of H. It is equal to X
10
00:00:58.840 --> 00:01:07.150 A:middle L:90%
times the derivative of G less g of X runs
11
00:01:07.150 --> 00:01:12.450 A:middle L:90%
the derivative of we're gonna plug in four for X
12
00:01:15.140 --> 00:01:22.840 A:middle L:90%
when we get equal to two times negative three list
13
00:01:23.040 --> 00:01:32.769 A:middle L:90%
by I'm six is equal to 24 For part C
14
00:01:33.340 --> 00:01:36.849 A:middle L:90%
, we have a TSH is a quotient of f
15
00:01:36.909 --> 00:01:42.010 A:middle L:90%
N g. So the derivative is equal to G
16
00:01:42.010 --> 00:01:47.349 A:middle L:90%
times the derivative minus half times the derivative of G
17
00:01:47.939 --> 00:01:55.219 A:middle L:90%
all over G square. This becomes equal to the
18
00:01:55.219 --> 00:02:00.620 A:middle L:90%
derivative of each of four is equal to G of
19
00:02:00.629 --> 00:02:07.729 A:middle L:90%
four terms, the derivative of F A four minus
20
00:02:07.740 --> 00:02:13.849 A:middle L:90%
up before times the derivative of G of four,
21
00:02:15.840 --> 00:02:27.349 A:middle L:90%
all over G of four square, which is equal
22
00:02:27.349 --> 00:02:40.060 A:middle L:90%
to 36 over 25 for party we have you of
23
00:02:40.069 --> 00:02:45.909 A:middle L:90%
X. We're gonna make that equal F X plus
24
00:02:45.919 --> 00:02:53.889 A:middle L:90%
g of vets. So you Is this some of
25
00:02:53.900 --> 00:02:58.979 A:middle L:90%
f n g? Thank you. The derivative of
26
00:02:58.979 --> 00:03:01.189 A:middle L:90%
you is equal to when you add the derivative of
27
00:03:01.219 --> 00:03:07.780 A:middle L:90%
us I n g each is a quotient of g
28
00:03:07.780 --> 00:03:10.409 A:middle L:90%
of X and you have X So we get each
29
00:03:10.409 --> 00:03:19.150 A:middle L:90%
of X g over you. The derivative is equal
30
00:03:19.159 --> 00:03:23.460 A:middle L:90%
to you. How's the derivative of G minus G
31
00:03:23.460 --> 00:03:27.750 A:middle L:90%
tons The derivative of you all over. You swear
32
00:03:29.539 --> 00:03:37.960 A:middle L:90%
I'll continue here we get a tch, the derivative
33
00:03:37.969 --> 00:03:43.460 A:middle L:90%
of X, and this is equal to f of
34
00:03:43.469 --> 00:03:53.330 A:middle L:90%
X plus g of nuts. Times the derivative of
35
00:03:53.330 --> 00:04:03.250 A:middle L:90%
G minus G of X times the derivative of X
36
00:04:04.439 --> 00:04:12.039 A:middle L:90%
plus, the derivative of G of X, all
37
00:04:12.050 --> 00:04:26.139 A:middle L:90%
over ever backs less g of x square. When
38
00:04:26.139 --> 00:04:30.649 A:middle L:90%
we put this in, we got two plus four
39
00:04:32.740 --> 00:04:44.250 A:middle L:90%
two plus five excusing arms negative three minus by I'm
40
00:04:44.250 --> 00:04:50.050 A:middle L:90%
six minus three because you're adding negative three and he
41
00:04:50.050 --> 00:04:59.579 A:middle L:90%
divide this over to plus five square to get 36
42
00:05:02.779 --> 00:05:06.529 A:middle L:90%
over 49 negative
