Question

How do you Use a Riemann sum to find area?

Answer 1

Calculating the area under a curve using Riemann sums. Given a function f(x) where f(x)≥0 over an interval a≤x≤b, we investigate the area of the region that is under the graph of f(x) and above the interval [a,b] on the x-axis. As illustrated in the following figure, we divide the interval [a,b] into n subintervals
