00:00:00.500 --> 00:00:03.919 A:middle L:90%
problem is part a. Find the intervals on which
2
00:00:03.930 --> 00:00:07.969 A:middle L:90%
half its increasing our secreting are to be finding the
3
00:00:07.969 --> 00:00:12.259 A:middle L:90%
local maximum and minimum values of five. Have C
4
00:00:12.470 --> 00:00:16.350 A:middle L:90%
find the intervals off can committee and inflection points.
5
00:00:16.940 --> 00:00:20.239 A:middle L:90%
I thought blacks is he goto, assigning square minus
6
00:00:20.239 --> 00:00:24.920 A:middle L:90%
two times sighing. Axe Axe is between zero and
7
00:00:24.929 --> 00:00:29.850 A:middle L:90%
two pi. It's a four way first to a
8
00:00:29.850 --> 00:00:35.159 A:middle L:90%
computer half axe problem, which is equal to who
9
00:00:35.159 --> 00:00:40.250 A:middle L:90%
would harm school. Cy Axe. I'm negative kayaks
10
00:00:41.640 --> 00:00:46.229 A:middle L:90%
minus two times cause I X, which is the
11
00:00:46.229 --> 00:00:53.149 A:middle L:90%
court with two times Kasai axe times elective fine max
12
00:00:54.850 --> 00:01:00.549 A:middle L:90%
minus one. If we lie to half axe from
13
00:01:02.140 --> 00:01:07.250 A:middle L:90%
you called zero we have X is equal to hi
14
00:01:07.260 --> 00:01:15.109 A:middle L:90%
Over too war There is high over two. Then
15
00:01:15.109 --> 00:01:23.010 A:middle L:90%
we have the following results. If the interval it's
16
00:01:23.010 --> 00:01:30.319 A:middle L:90%
between zero and pi over too, we have extra
17
00:01:30.329 --> 00:01:38.349 A:middle L:90%
foam. It's negative. So is Ik fizzy on
18
00:01:38.390 --> 00:01:45.420 A:middle L:90%
the interval? Hi Over too two three pile work
19
00:01:45.430 --> 00:01:55.019 A:middle L:90%
too. A fax prom is positive. Over half
20
00:01:55.030 --> 00:02:00.829 A:middle L:90%
half is increasing and I was an interval. Three
21
00:02:00.829 --> 00:02:12.830 A:middle L:90%
Pi over too, too high. So we have
22
00:02:14.120 --> 00:02:23.830 A:middle L:90%
affects prom. It's negative. So half is decreasing
23
00:02:27.219 --> 00:02:35.860 A:middle L:90%
B from the result in part a half What?
24
00:02:35.870 --> 00:02:40.229 A:middle L:90%
Max, It's the call to pie over to you
25
00:02:43.560 --> 00:02:49.840 A:middle L:90%
. A fax has a local minimum value, which
26
00:02:49.840 --> 00:02:54.979 A:middle L:90%
is the cultural Cyril minus two, which is the
27
00:02:54.979 --> 00:03:00.039 A:middle L:90%
cultural negative, too. Axe is equal to three
28
00:03:00.039 --> 00:03:06.030 A:middle L:90%
pi over too. If has a maximum value,
29
00:03:07.819 --> 00:03:15.270 A:middle L:90%
which is equal to zero plus two is which is
30
00:03:15.270 --> 00:03:22.650 A:middle L:90%
equal to two. How to see first of a
31
00:03:22.650 --> 00:03:27.330 A:middle L:90%
compute second derivative off half a box, which is
32
00:03:27.330 --> 00:03:37.979 A:middle L:90%
equal to who would have negative flying Axe Ham's effective
33
00:03:37.990 --> 00:03:45.729 A:middle L:90%
sign Axe minus one class two halves Cose I X
34
00:03:46.289 --> 00:03:53.580 A:middle L:90%
Ham's elective course I X, which is equal to
35
00:03:55.319 --> 00:04:04.439 A:middle L:90%
two times sine X squire. Plus who would have
36
00:04:04.449 --> 00:04:10.729 A:middle L:90%
thought I x minus to co sign X koi.
37
00:04:10.750 --> 00:04:15.449 A:middle L:90%
So here we minus two cams. One minus sign
38
00:04:15.379 --> 00:04:19.620 A:middle L:90%
. Ex corde, we're half. This is Echo
39
00:04:19.620 --> 00:04:30.040 A:middle L:90%
two two times Sign Axe plus one comes to find
40
00:04:30.050 --> 00:04:42.519 A:middle L:90%
X minus one. Observation with half What affects prom
41
00:04:42.519 --> 00:04:46.800 A:middle L:90%
. Prom. So the second derivative changes size one
42
00:04:47.740 --> 00:04:55.250 A:middle L:90%
sign acts is because of you. Half you will
43
00:04:55.250 --> 00:05:00.250 A:middle L:90%
have axe is equal to pi over a six or
44
00:05:00.980 --> 00:05:10.189 A:middle L:90%
while high over six. So your half into a
45
00:05:10.189 --> 00:05:16.939 A:middle L:90%
ll zero two pi over six behalf second derivative is
46
00:05:17.129 --> 00:05:26.500 A:middle L:90%
negative. The function come calf downward on into Opie
47
00:05:26.500 --> 00:05:30.920 A:middle L:90%
over six to five. High over six. Second
48
00:05:30.920 --> 00:05:35.860 A:middle L:90%
derivative. It's positive. The function conch. If
49
00:05:35.870 --> 00:05:42.069 A:middle L:90%
up, as in Toronto, file pie over six
50
00:05:43.740 --> 00:05:47.019 A:middle L:90%
. You are too high. A secondary motive is
51
00:05:47.029 --> 00:05:54.449 A:middle L:90%
selective. The function, Kev. Downward. Yeah
52
--> A:middle L:90%
.
