Riemann Sums, Left Endpoints
Calculus-Integrals: Approximating AreaDownloadable Video - 2015
When you use a Riemann sum to approximate the area under the curve, you're just sketching rectangles under the curve, taking the area of each rectangle, and then adding the areas together. When you use left endpoints, it means that you draw the rectangles such that their upper-left corners touch the curve.
