So let's evaluate that given what we just were able to derive. So our volume, I'll do it up here. The volume is going to be the integral. What are the two intersection points? Well, over here, once again, we could have defined the interval someplace else, like between there and there, and we would have gotten a different shape, but the points that we care about, the way we visualize it is between x is equal to zero, x is equal to zero, and x is equal to one. That's where these two things intersect. We saw that in the last video.
