Here, we want to estimate the area underneath the graph of a positive function by 4 ,000 rectangles of equal width.
00:10
And we want to know what will be the best estimate.
00:13
So i'd like to point out a couple of things.
00:15
First off, we know that it's positive.
00:19
Does that matter? i would argue no.
00:22
Being positive doesn't really tell us anything.
00:25
Also, 4 ,000 rectangles.
00:28
Well, using 4 ,000 rectangles tells us it's probably going to be more.
00:31
Accurate than using 100 or 5.
00:34
A large number of rectangles means it's probably going to be pretty accurate, but we're not guaranteed that...
