Okay, so let's find delta x first.
00:03
Delta x is 2 minus 0 over 5, which is 0 .4.
00:07
Okay, so i'm going to go like this, 0 .4, 0 .8, 1.
00:20
I mean 1 .2, not 1 .1 .2, 1 .6, and 2.
00:27
Now we need the midpoint, so that's why i left that.
00:30
So 0 .2, 0 .6, 1, 1 .4, and 1 .8.
00:38
And we need those function values, okay? so 0 .2 will give me 6 .04, 0 .6 will give me 6 .36, 1 will give me 7, right? and then 1 .4 will give me 7 .96, and 1 .8 will give me 9 .24.
01:12
Okay, so delta x, which is 0 .4 times, we're going to add them all up.
01:25
0 .96 plus 9 .24...
