They could be equal sections or not, but let's just say for the sake of visualizations, I'm gonna draw roughly equal sections here. So that's the first, that's the second, this is the third, this is the fourth, this is the fifth, and then we have the sixth right over here. And so each of these, this is delta x, let's just call that delta x one, this is delta x two, this width right over here, this is delta x three, all the way to delta x n. I'll try to be general here. And so what we could do is let's try to sum up the area of the rectangles defined here. And we could make the height, maybe we make the height based on the value of the function at the right bound. It doesn't have to be, it could be the value of the function someplace in this delta x. But that's one solution.
