Okay. This question says to estimate the integral of
2
00:00:05.040 --> 00:00:09.650 A:middle L:90%
power to find the total energy consumption, and it
3
00:00:09.650 --> 00:00:13.669 A:middle L:90%
wants us to use Simpson's rule. So to do
4
00:00:13.669 --> 00:00:17.109 A:middle L:90%
this, remember that Simpson's rule says the integral from
5
00:00:17.109 --> 00:00:20.989 A:middle L:90%
A to B of f of x d X is
6
00:00:20.989 --> 00:00:27.059 A:middle L:90%
approximately equal to the Simpson approximation, which is Delta
7
00:00:27.059 --> 00:00:37.359 A:middle L:90%
X over three times Fok, plus for times the
8
00:00:37.369 --> 00:00:45.950 A:middle L:90%
odd terms plus two times that even terms plus F
9
00:00:45.950 --> 00:00:53.280 A:middle L:90%
a B. So from there, we just need
10
00:00:53.280 --> 00:00:57.000 A:middle L:90%
to pick our value. And so there are 13
11
00:00:57.000 --> 00:01:00.000 A:middle L:90%
data points in the table. And remember, R
12
00:01:00.009 --> 00:01:06.609 A:middle L:90%
N value is always one less than the total number
13
00:01:06.609 --> 00:01:10.420 A:middle L:90%
of puts. So pick an even number and equals
14
00:01:10.420 --> 00:01:15.450 A:middle L:90%
12. So that means that Delta X equals well
15
00:01:15.939 --> 00:01:19.250 A:middle L:90%
, we're ending at six, starting at zero,
16
00:01:19.840 --> 00:01:22.849 A:middle L:90%
and we want 12 sub intervals. So if 1/2
17
00:01:23.390 --> 00:01:29.049 A:middle L:90%
so that means that s a 12 is equal to
18
00:01:30.340 --> 00:01:38.909 A:middle L:90%
1/2 divided by three, which is 1/6 times off
19
00:01:38.909 --> 00:01:47.239 A:middle L:90%
of zero plus four times F of 40.5 plus two
20
00:01:47.250 --> 00:01:53.439 A:middle L:90%
times f of one plus four times F 4.5.
21
00:01:53.840 --> 00:02:06.750 A:middle L:90%
Plus I just I thought four f 5.5 plus half
22
00:02:06.750 --> 00:02:09.009 A:middle L:90%
of six. And then, if you go through
23
00:02:09.050 --> 00:02:13.080 A:middle L:90%
and punch all of these function values and your calculator
24
00:02:13.740 --> 00:02:27.120 A:middle L:90%
, you'll see that s 12 equals 10 177 megawatt
25
00:02:27.129 --> 00:02:37.949 A:middle L:90%
hours, and that's approximately equal to energy.
