It could be the value of the function someplace in this delta x.
And we could make the height, maybe we make the height based on the value of theįunction at the right bound. Let's try to sum up the area of the rectangles defined here. This is delta x three, all the way to delta x n. And so each of these, this is delta x, let's just call that delta x one. The sake of visualizations, I'm gonna draw roughlyĮqual sections here. They could be equal sections or not, but let's just say, for How would you do it? Well, you could divide this section into a bunch of delta Well, without calculus, you could actually get better and betterĪpproximations for it. So let me draw theseīoundaries right over here. How do we find the area under this curve? Maybe under the curveĪnd above the x-axis, and let's say between two boundaries. So I have a curve here that represents y is equal to f of x, and there's a classic problem that mathematicians
