So i'm given the function y equals 1 over x, and i'm on the interval from 1 to 2.
00:09
I want to use 1, 2, 3, 4, 5 rectangles.
00:17
So, first thing i'm going to do is find the width of my rectangles, which is 1 over 5, or 0 .2.
00:29
I'm going to make a number line, and then i'm going to, i'll let this be f of x.
00:42
So i'm going to want f of 1, 1 .2, 1 .4, 1 .6, and 1 .8 for one of them.
00:55
And then i'm going to want 2, 1 .8, 1 .6, 1 .4, and 1 .2 for the other.
01:08
I'm going to do them at the same time, just to simplify things a little bit.
01:13
If i put in 1, i'm going to get out 1.
01:16
If i put in 2, i'm going to get out 0 .5...
