And you can even approximate it. I mean, one way you could approximate it is you could use it the way you approximate integrals in general, where you could say, well, what is the area of this? What's roughly the area of this trapezoid? So you could figure out the area of that trapezoid, taking the average of that point and that point and multiplying it by the base. Or you could just take the level of the, let me change colors, just because I think I'm overdoing it with the green, or you could just take the height of this line right here and multiply it by the base. And you'll get the area of this rectangle, which might be a pretty good approximation for the area under the curve, right, because you'll have a little bit extra over here, but you're going to miss a little bit over there. So it might be a pretty good approximation.
