00:00:01.240 --> 00:00:04.230 A:middle L:90%
it's clear. So when you married here So we
2
00:00:04.230 --> 00:00:13.949 A:middle L:90%
have d of clash of that's over. D s
3
00:00:17.839 --> 00:00:26.010 A:middle L:90%
is equal to 1/2 de eat the X Let's eat
4
00:00:26.010 --> 00:00:35.729 A:middle L:90%
to the negative x over d x This becomes equal
5
00:00:35.740 --> 00:00:42.590 A:middle L:90%
to one huh of e to the X minus e
6
00:00:42.590 --> 00:00:53.049 A:middle L:90%
to the negative x so they see that D of
7
00:00:53.640 --> 00:01:00.609 A:middle L:90%
D over DX of caution is equal to the high
8
00:01:00.609 --> 00:01:14.000 A:middle L:90%
public function of sign. For part B, we
9
00:01:14.000 --> 00:01:19.109 A:middle L:90%
have the 10 which is equal to sign over.
10
00:01:19.120 --> 00:01:22.530 A:middle L:90%
It's not co sign when we get e to the
11
00:01:22.540 --> 00:01:27.959 A:middle L:90%
X miners, Pete the negative x all over e
12
00:01:29.049 --> 00:01:38.180 A:middle L:90%
to the X plus e to the negative x So
13
00:01:38.180 --> 00:01:49.150 A:middle L:90%
we're gonna differentiate you want over d X We eat
14
00:01:49.150 --> 00:01:55.920 A:middle L:90%
to the X minus B to the negative x the
15
00:01:55.920 --> 00:02:02.450 A:middle L:90%
derivative beach the X plus e to the negative x
16
00:02:07.140 --> 00:02:08.860 A:middle L:90%
minus e to the X minus each. The negative
17
00:02:08.870 --> 00:02:15.300 A:middle L:90%
bets That's a derivative of e to the X plus
18
00:02:15.310 --> 00:02:24.120 A:middle L:90%
eat. Then they go all over each the X
19
00:02:24.120 --> 00:02:34.169 A:middle L:90%
plus e to the negative explorer. We end up
20
00:02:34.169 --> 00:02:43.030 A:middle L:90%
getting e to the two x plus two plus eats
21
00:02:43.030 --> 00:02:47.949 A:middle L:90%
. The negative to X was too minus eats in
22
00:02:47.949 --> 00:02:55.650 A:middle L:90%
the negative to us all over b to the X
23
00:02:58.590 --> 00:03:05.879 A:middle L:90%
Let's eat the negative X square, which is equal
24
00:03:05.879 --> 00:03:14.500 A:middle L:90%
to two over e to the X plus e to
25
00:03:14.500 --> 00:03:27.479 A:middle L:90%
the negative X square. Then we get one over
26
00:03:28.840 --> 00:03:35.740 A:middle L:90%
you two x plus e to the negative X over
27
00:03:35.740 --> 00:03:39.750 A:middle L:90%
two square. We're just equal to one over the
28
00:03:39.750 --> 00:03:49.319 A:middle L:90%
high public function of CO sign square when we get
29
00:03:49.430 --> 00:04:02.150 A:middle L:90%
sequined square. No, that's report. See,
30
00:04:05.090 --> 00:04:09.770 A:middle L:90%
we have Coast seeking is equal to one over sign
31
00:04:13.340 --> 00:04:18.899 A:middle L:90%
which is equal to one over when, huh e
32
00:04:18.899 --> 00:04:21.519 A:middle L:90%
to the X minus e to the negative effects,
33
00:04:25.009 --> 00:04:28.949 A:middle L:90%
which is equal to two terms. Eat the explain
34
00:04:28.949 --> 00:04:32.050 A:middle L:90%
. It eats the negative eggs, the negative one
35
00:04:32.050 --> 00:04:35.259 A:middle L:90%
power we differentiate. Do you? Why? Over
36
00:04:35.259 --> 00:04:46.870 A:middle L:90%
d x we get negative two times negative one terms
37
00:04:46.879 --> 00:04:51.600 A:middle L:90%
Eat the X minus e to the negative effects to
38
00:04:51.600 --> 00:04:56.540 A:middle L:90%
the negative sucking power times The derivative of the two
39
00:04:56.610 --> 00:05:01.290 A:middle L:90%
x minus e. The negative butts, which is
40
00:05:01.290 --> 00:05:10.829 A:middle L:90%
equal to negative two over e to the X minus
41
00:05:10.839 --> 00:05:15.089 A:middle L:90%
, eats the negative. X comes eats the X
42
00:05:15.089 --> 00:05:19.329 A:middle L:90%
plus e to the negative effects all over e to
43
00:05:19.329 --> 00:05:25.550 A:middle L:90%
the X minus negative each. That's negative. It's
44
00:05:27.540 --> 00:05:36.410 A:middle L:90%
which is equal to negative. Cosi Comte Times Co
45
00:05:36.410 --> 00:05:47.759 A:middle L:90%
Sign over Sign This is equal to negative coast.
46
00:05:47.759 --> 00:06:02.579 A:middle L:90%
He can't times put engines for party. We're gonna
47
00:06:02.579 --> 00:06:15.129 A:middle L:90%
do another proof. So we get second is equal
48
00:06:15.129 --> 00:06:21.290 A:middle L:90%
to one over co sign jizzy bolted to beat the
49
00:06:21.290 --> 00:06:26.149 A:middle L:90%
X plus e to the negative extra negative first power
50
00:06:27.939 --> 00:06:46.149 A:middle L:90%
we differentiate and then we get negative one times two
51
00:06:46.540 --> 00:06:50.430 A:middle L:90%
each the X plus e to the negative extra second
52
00:06:50.430 --> 00:06:59.490 A:middle L:90%
power times eat the eggs plus e to the negative
53
00:06:59.500 --> 00:07:06.069 A:middle L:90%
x the derivative. This becomes equal to negative too
54
00:07:08.839 --> 00:07:11.170 A:middle L:90%
well over e to the X plus e to the
55
00:07:11.170 --> 00:07:17.430 A:middle L:90%
negative X worms Eat the oneness e to the negative
56
00:07:17.430 --> 00:07:23.620 A:middle L:90%
effects all over e to the X plus eats the
57
00:07:23.620 --> 00:07:31.519 A:middle L:90%
negative x the second port. It becomes 1/2 e
58
00:07:31.519 --> 00:07:34.759 A:middle L:90%
to the x minus e to the negative x over
59
00:07:34.759 --> 00:07:39.449 A:middle L:90%
1/2 b to the X plus each the negative x
60
00:07:40.079 --> 00:07:46.279 A:middle L:90%
Jake's equal to negative The hyperbole function of secrets I'm
61
00:07:46.279 --> 00:07:58.649 A:middle L:90%
sign over co sign just equal to the negative sequence
62
00:08:01.500 --> 00:08:11.829 A:middle L:90%
and the hiker of like function of tangent her e
63
00:08:11.829 --> 00:08:22.839 A:middle L:90%
we're looking at cu attention. Is it equal to
64
00:08:22.850 --> 00:08:28.699 A:middle L:90%
each the explosive e to the negative X all over
65
00:08:28.709 --> 00:08:35.460 A:middle L:90%
each the X minus e to the negative effects when
66
00:08:35.460 --> 00:08:39.559 A:middle L:90%
we get the derivative equal to eat to the X
67
00:08:39.559 --> 00:08:48.100 A:middle L:90%
plus each the negative driven it off that pizza X
68
00:08:48.110 --> 00:08:56.159 A:middle L:90%
minus E to the negative effects minus eat X plus
69
00:08:56.169 --> 00:09:05.149 A:middle L:90%
eats and negative X terms each the X minus each
70
00:09:05.149 --> 00:09:09.470 A:middle L:90%
than negative X and the derivative function that all over
71
00:09:09.470 --> 00:09:16.000 A:middle L:90%
e to the x minus e to the negative x
72
00:09:16.000 --> 00:09:28.809 A:middle L:90%
where which becomes equal to negative to over eat the
73
00:09:28.809 --> 00:09:37.639 A:middle L:90%
X minus. Eat the negative X square, which
74
00:09:37.639 --> 00:09:43.429 A:middle L:90%
is equal to one over negative one over. I
75
00:09:43.429 --> 00:09:54.970 A:middle L:90%
probably function of sign when we got co Siegen Negative
