Well, without calculus, you could actually get better and better approximations for it. How would you do it? Well, you could divide this section into a bunch of delta x's that go from a to b. 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.
