Riemann Sums (Left Hand & Right Hand Approximation)

This Calculus 1 video explains how to use left hand and right hand Riemann sums to approximate the area under a curve on some interval. We explain the notation for Riemann sums, subintervals, and how to calculate delta x (the width of each rectangle). We work the same example as both a left endpoint approximation and a right endpoint approximation. We also show how using more rectangles gives us a more accurate approximation.
