1
00:00:00.340 --> 00:00:04.209 A:middle L:90%
okay. Discussion were able to solve interrogation of sine
2
00:00:04.209 --> 00:00:09.560 A:middle L:90%
X, divided by one plus courses Square X DX
3
00:00:09.939 --> 00:00:12.250 A:middle L:90%
. Okay. And the limit is by by two
4
00:00:12.640 --> 00:00:15.410 A:middle L:90%
by. Okay, so first of all, we
5
00:00:15.410 --> 00:00:18.760 A:middle L:90%
will rewrite. Our question is, it will be
6
00:00:19.760 --> 00:00:26.070 A:middle L:90%
sign X B X divided by one Plus. It
7
00:00:26.070 --> 00:00:28.550 A:middle L:90%
will be co sex. Holy square. Okay,
8
00:00:28.559 --> 00:00:32.009 A:middle L:90%
so in the denominator, we have perfect spare.
9
00:00:32.020 --> 00:00:34.890 A:middle L:90%
Okay? And now we will do the substitution process
10
00:00:34.899 --> 00:00:38.079 A:middle L:90%
and we will take you equals two Cossacks That will
11
00:00:38.079 --> 00:00:42.090 A:middle L:90%
give us the U equals two minus sine x dx
12
00:00:42.100 --> 00:00:46.170 A:middle L:90%
. OK, And before substituting, we have to
13
00:00:46.170 --> 00:00:49.090 A:middle L:90%
recommend the new parliamentary lower limit. Then the lower
14
00:00:49.090 --> 00:00:52.560 A:middle L:90%
limit will be okay. Then the lower limit will
15
00:00:52.560 --> 00:00:55.979 A:middle L:90%
be so lower Limit for the given X is bye
16
00:00:55.979 --> 00:00:58.340 A:middle L:90%
bye to that is given. And we have assumed
17
00:00:58.340 --> 00:01:00.640 A:middle L:90%
the U equals two co sex. Then you will
18
00:01:00.640 --> 00:01:03.030 A:middle L:90%
be because access by by two. Then you will
19
00:01:03.030 --> 00:01:06.159 A:middle L:90%
be caused by where to. Then it will be
20
00:01:06.170 --> 00:01:10.340 A:middle L:90%
zero okay. And a parliament. Okay. And
21
00:01:10.340 --> 00:01:12.290 A:middle L:90%
for a par limit, X equals two pi is
22
00:01:12.290 --> 00:01:15.609 A:middle L:90%
given and U equals two Cossacks. Then it will
23
00:01:15.609 --> 00:01:19.239 A:middle L:90%
be u equals to cause pie that is minus one
24
00:01:19.250 --> 00:01:23.379 A:middle L:90%
Okay, So lower limit is zero and a parliament
25
00:01:23.379 --> 00:01:26.659 A:middle L:90%
is minus one. Here. Okay. And now
26
00:01:26.670 --> 00:01:29.060 A:middle L:90%
we will do the substitution, and it will be
27
00:01:29.540 --> 00:01:32.739 A:middle L:90%
lower. Limit zero. Parliament minus one. Okay
28
00:01:32.799 --> 00:01:36.390 A:middle L:90%
. And in the numerator sign X dx. OK
29
00:01:36.469 --> 00:01:38.730 A:middle L:90%
, that is equal to minus D you okay?
30
00:01:38.739 --> 00:01:42.060 A:middle L:90%
Minus d'you. Divided by one plus Cossacks, is
31
00:01:42.060 --> 00:01:45.159 A:middle L:90%
you that it will be us square. Okay,
32
00:01:45.540 --> 00:01:47.920 A:middle L:90%
now it is a simple question. We have to
33
00:01:47.920 --> 00:01:49.400 A:middle L:90%
solve this, and we know. Do you divided
34
00:01:49.400 --> 00:01:52.920 A:middle L:90%
by one plus you square and its integration will be
35
00:01:52.930 --> 00:01:55.689 A:middle L:90%
our 10. You okay? It will be minus
36
00:01:55.989 --> 00:01:59.769 A:middle L:90%
and arc, then you okay? And the limited
37
00:01:59.769 --> 00:02:04.159 A:middle L:90%
zero to minus one. So it will be minus
38
00:02:04.840 --> 00:02:09.759 A:middle L:90%
are 10 minus one miners, our 10 and lower
39
00:02:09.759 --> 00:02:14.819 A:middle L:90%
limit zero. Okay, it will be minus 10
40
00:02:14.819 --> 00:02:16.300 A:middle L:90%
watts minus one that is minus by by four.
41
00:02:16.620 --> 00:02:21.860 A:middle L:90%
Okay. Minus zero. Okay. And minus minus
42
00:02:21.860 --> 00:02:24.069 A:middle L:90%
. Plus their tastes, plus by my four.
43
00:02:24.120 --> 00:02:28.259 A:middle L:90%
And that will be our final answer. Thank you
44
--> A:middle L:90%
