00:00:00.740 --> 00:00:03.149 A:middle L:90%
Okay, so here we have this double inner girl
2
00:00:03.149 --> 00:00:10.169 A:middle L:90%
. Three to four and two of the function,
3
00:00:10.169 --> 00:00:15.689 A:middle L:90%
six x over five. Plus, why ever X
4
00:00:18.640 --> 00:00:25.390 A:middle L:90%
And that's the extra y. So first, we
5
00:00:25.390 --> 00:00:27.670 A:middle L:90%
want to take an anti derivative here with respect to
6
00:00:27.679 --> 00:00:32.289 A:middle L:90%
X keeping. Why fixed? So that ends up
7
00:00:32.299 --> 00:00:36.539 A:middle L:90%
being three x squared over five. I mean,
8
00:00:36.539 --> 00:00:39.850 A:middle L:90%
that x x squared over two. Plus, why
9
00:00:40.729 --> 00:00:49.409 A:middle L:90%
long absolute value of X evaluated from one to in
10
00:00:49.409 --> 00:00:51.939 A:middle L:90%
that function of libel, integrate with respected by.
11
00:00:53.740 --> 00:00:57.820 A:middle L:90%
Okay, so we can just evaluate the's in points
12
00:00:57.920 --> 00:01:03.049 A:middle L:90%
x squared. So we force this is going to
13
00:01:03.049 --> 00:01:07.150 A:middle L:90%
be three fifths. Two squared, minus one squared
14
00:01:08.409 --> 00:01:14.430 A:middle L:90%
. Plus why? Times Law of two minds Log
15
00:01:14.430 --> 00:01:18.280 A:middle L:90%
of Warren. Remember that log of one zero?
16
00:01:19.939 --> 00:01:23.180 A:middle L:90%
Okay, do you want? So this is just
17
00:01:23.180 --> 00:01:26.400 A:middle L:90%
the inner girl from three to four. So you're
18
00:01:26.400 --> 00:01:29.980 A:middle L:90%
going to be three. So that will be nine
19
00:01:29.989 --> 00:01:37.750 A:middle L:90%
fifths. Plus. Why? Log of two?
20
00:01:38.870 --> 00:01:42.549 A:middle L:90%
It's like one zero. Okay, now, just
21
00:01:42.780 --> 00:01:47.069 A:middle L:90%
taken an anti derivative with respect to why said nine
22
00:01:47.069 --> 00:01:49.549 A:middle L:90%
fifths. Why? Plus why squared over two?
23
00:01:51.239 --> 00:01:55.150 A:middle L:90%
Walk to how you waited from three to four.
24
00:01:57.040 --> 00:02:00.310 A:middle L:90%
Could appear. Okay, so then if I evaluate
25
00:02:00.310 --> 00:02:02.623 A:middle L:90%
Why? From three to four that just gives me
26
00:02:02.623 --> 00:02:07.133 A:middle L:90%
once I get nine, Sure. And then why
27
00:02:07.133 --> 00:02:15.193 A:middle L:90%
squared? Evaluated from four squared minus three squared?
28
00:02:15.203 --> 00:02:19.793 A:middle L:90%
That's sixteen a minus nine. That seven. So
29
00:02:19.862 --> 00:02:23.032 A:middle L:90%
seven over two look two.
