00:00:00.540 --> 00:00:04.250 A:middle L:90%
you have a question and this we need to find
2
00:00:04.839 --> 00:00:09.220 A:middle L:90%
there acute angles between two curves at the points of
3
00:00:09.220 --> 00:00:12.759 A:middle L:90%
intersection. So let us write down the car's first
4
00:00:13.339 --> 00:00:16.160 A:middle L:90%
. Why can't you accept square and why can't two
5
00:00:16.160 --> 00:00:18.949 A:middle L:90%
XQ. That point of the section will be by
6
00:00:18.960 --> 00:00:26.760 A:middle L:90%
creating access square an X. Q. Okay so
7
00:00:26.769 --> 00:00:29.219 A:middle L:90%
access square will be taken as common. The X
8
00:00:29.219 --> 00:00:34.649 A:middle L:90%
-1 equal to zero Sex equal to zero and when
9
00:00:35.439 --> 00:00:37.969 A:middle L:90%
so if X equal to zero and one. So
10
00:00:37.969 --> 00:00:40.850 A:middle L:90%
why will also be equal to zero and one point
11
00:00:40.850 --> 00:00:47.450 A:middle L:90%
of intersections will be zero comma zero and one comer
12
00:00:48.140 --> 00:00:52.990 A:middle L:90%
. What? No um the acute angle to find
13
00:00:52.990 --> 00:01:00.810 A:middle L:90%
acute angle so acute angle between two curves is at
14
00:01:00.820 --> 00:01:03.890 A:middle L:90%
any point is the acute angle formed by the attendance
15
00:01:03.890 --> 00:01:07.030 A:middle L:90%
at that point. For that. We need to
16
00:01:07.030 --> 00:01:08.689 A:middle L:90%
get the slope of the tangent. So let us
17
00:01:08.689 --> 00:01:12.629 A:middle L:90%
get the value of anyone by differentiating who I call
18
00:01:12.629 --> 00:01:17.689 A:middle L:90%
to access choir with respect to X two X and
19
00:01:17.700 --> 00:01:21.659 A:middle L:90%
M2 will be equal to developed by the X in
20
00:01:21.659 --> 00:01:26.829 A:middle L:90%
this case three X square. So everyone at zero
21
00:01:26.829 --> 00:01:30.739 A:middle L:90%
is 0 and M two at zero is zero and
22
00:01:30.739 --> 00:01:37.409 A:middle L:90%
one at x equal to one is 2 and AM
23
00:01:37.409 --> 00:01:41.299 A:middle L:90%
two XX equal to one is 3. So acute
24
00:01:41.310 --> 00:01:48.989 A:middle L:90%
angle we know that tan theta is am one minus
25
00:01:48.989 --> 00:01:52.849 A:middle L:90%
M two by one place and want him to mud
26
00:01:53.540 --> 00:01:59.299 A:middle L:90%
10 30 will be M one to minus three By
27
00:01:59.299 --> 00:02:07.090 A:middle L:90%
1-plus 6 model S So 10 Theta will be-1
28
00:02:07.090 --> 00:02:10.110 A:middle L:90%
x seven modelers which means Then think I will be
29
00:02:10.110 --> 00:02:20.969 A:middle L:90%
equal to plus-1 by seven. Yeah so angles
30
00:02:20.969 --> 00:02:27.159 A:middle L:90%
will be data either then in verse one by seven
31
00:02:27.840 --> 00:02:30.860 A:middle L:90%
which will be able to turn in verse one by
32
00:02:32.039 --> 00:02:42.460 A:middle L:90%
mm eight point well three degrees or theater too.
33
00:02:42.840 --> 00:02:50.860 A:middle L:90%
Getting worse-1 x seven. The universe mine is
34
00:02:50.860 --> 00:03:00.759 A:middle L:90%
run by So this is-8 13 degrees-8.130 DB
35
00:03:00.240 --> 00:03:04.439 A:middle L:90%
. Well, this could be done is Uh one
36
00:03:04.439 --> 00:03:08.860 A:middle L:90%
of the 80 minus. Okay, so this is
37
00:03:08.860 --> 00:03:13.120 A:middle L:90%
going to be obtuse angle, So acute angle is
38
00:03:13.129 --> 00:03:15.060 A:middle L:90%
8.13°. Thank you.
