This lesson involves comparing the Riemann Sum area estimates with the exact bounded area of a curve and the x-axis.

The approximate value at each midpoint is below.

This approximation through the area of rectangles is known as a Riemann sum. Additional Examples with Fixed Numbers of Rectangles Riemann Sum Calculator is a free online tool that displays the approximation of an integral using finite sum. BYJU’S online Riemann sum calculator tool makes the calculation faster and it displays the Riemann sum in a fraction of seconds. How to Use the Riemann Sum Calculator?

Lastly, we will look at the idea of infinite sub-intervals (which leads to integrals) to exactly calculate the area under the curve. A Riemann sum is simply a sum of products of the form $$f (x^∗_i )\Delta x$$ that estimates the area between a positive function and the horizontal axis over a given interval.

Riemann Sums Definition A Riemann sum is a way to approximate the area under a curve using a series of rectangles; These rectangles represent pieces of the curve called subintervals (sometimes called subdivisions or partitions). Riemann Sums Consider again \ (\int_0^4 (4x-x^2)dx\).
