So that's our second one, all the way until this one right over here is going to be our nth one. So this is one, let me write it this way. This is i is equal to one, this is i is equal to two, all the way until we get to i is equal to n. And then if we take the limit as n approaches infinity, the sum of the areas of these rectangles are going to get better and better and better. And so let's first think about it. What is the width of each of these rectangles going to be? Well, I am taking this interval from pi to two pi, and I'm gonna divide it into n equal intervals. So the width of each of these, the width of each of these, is going to be two pi minus pi.
