Okay, so we're given the function x cubed on the interval of five to six.
00:03
We want to construct a remand sum using right endpoints.
00:08
So let's give an interval.
00:09
So this is what x cube looks like, at least in the first quadrant.
00:13
I'm going to try it a little thinner because it kind of grows a little quicker than that.
00:15
So maybe something like this.
00:19
Okay, maybe this is five and this is six right here.
00:23
What we're going to do is we're going to construct rectangles.
00:26
I'm going to keep doing it, such that they represent the error end of the curve.
00:29
This will end up being a, if we add all these rectangles, areas together, we'll get an approximation.
00:33
The more rectangles we use, the more close that approximation will be...
