But that's what its use is. It happens kind of when you start taking an infinite number of steps. But it can approximate the discrete. And the way I approximate it is I say, oh, what's the probability of being within a foot of that? And so I multiply this height, which I calculate here, times 1. So let's say this has a base of 1 to calculate this area, which I use as an approximation. So you just multiply that times 1, and that's what you get here.
