00:00:00.390 --> 00:00:03.600 A:middle L:90%
Let's start off here by just rewriting co tangent.
2
00:00:09.240 --> 00:00:11.759 A:middle L:90%
So using the definition of cool attention, we can
3
00:00:11.759 --> 00:00:19.359 A:middle L:90%
write this as co sign eggs over Sine X and
4
00:00:19.359 --> 00:00:28.940 A:middle L:90%
then on the bottom. And then let's go ahead
5
00:00:28.940 --> 00:00:37.810 A:middle L:90%
and simplify these fractions and we can breathe right.
6
00:00:37.810 --> 00:00:44.719 A:middle L:90%
This is sine X plus four co sign and then
7
00:00:44.719 --> 00:00:50.130 A:middle L:90%
you have four sign minus co sign after cancelling out
8
00:00:50.130 --> 00:00:55.549 A:middle L:90%
those signs. This is what we have now.
9
00:00:55.549 --> 00:00:57.850 A:middle L:90%
From this point, let's go ahead and try Yusa
10
00:00:59.539 --> 00:01:07.599 A:middle L:90%
, take you to be that denominator. Then we
11
00:01:07.599 --> 00:01:17.989 A:middle L:90%
know that, do you? Dx And that's precisely
12
00:01:17.989 --> 00:01:21.569 A:middle L:90%
what we see over here in the numerator four Co
13
00:01:21.569 --> 00:01:29.290 A:middle L:90%
Zion plus I the ex. Also, we should
14
00:01:30.140 --> 00:01:33.450 A:middle L:90%
watch out for these limited generation. Those will change
15
00:01:34.840 --> 00:01:38.430 A:middle L:90%
. So to find out there you values go ahead
16
00:01:38.430 --> 00:01:42.549 A:middle L:90%
and plug in these X values into the use of
17
00:01:44.140 --> 00:01:53.799 A:middle L:90%
So if X equals power for so just go right
18
00:01:53.799 --> 00:02:00.677 A:middle L:90%
ahead. Plug in pie before in for X for
19
00:02:00.677 --> 00:02:02.718 A:middle L:90%
room two over too. Bring two over too.
20
00:02:05.108 --> 00:02:09.048 A:middle L:90%
So three radical to over too. That's our new
21
00:02:09.048 --> 00:02:12.437 A:middle L:90%
lower limit. And for the upper limit, go
22
00:02:12.437 --> 00:02:15.497 A:middle L:90%
ahead and plug in pirate too, and Rex and
23
00:02:15.497 --> 00:02:21.768 A:middle L:90%
there you'LL get four minus zero equals four. So
24
00:02:21.768 --> 00:02:27.087 A:middle L:90%
we can rewrite this three root, too over to
25
00:02:27.117 --> 00:02:31.538 A:middle L:90%
before, and then we just have one over you
26
00:02:32.657 --> 00:02:38.967 A:middle L:90%
. Do you recall the D'You accounts for this over
27
00:02:38.967 --> 00:02:44.018 A:middle L:90%
here and then the yuan The denominator corresponds to this
28
00:02:45.707 --> 00:02:49.168 A:middle L:90%
two. It's evaluate that in a rule that's natural
29
00:02:49.168 --> 00:02:52.858 A:middle L:90%
, odd, absolute value, you then go ahead
30
00:02:52.858 --> 00:02:54.587 A:middle L:90%
and plug in three and room to over two and
31
00:02:54.587 --> 00:02:59.918 A:middle L:90%
four and then just subtract these end points and simplify
32
00:03:00.457 --> 00:03:05.348 A:middle L:90%
and you'LL get it. Four article, too over
33
00:03:05.348 --> 00:03:09.018 A:middle L:90%
three inside the longer them and that's your final answer
34
--> A:middle L:90%
.
