Riemann Sums

Riemann sums, introduced by Bernhard Riemann in the mid-19th century, are a mathematical technique used to approximate the area under a curve. In this lesson, we will delve into the process of estimating the definite integral of a function over a given interval. This involves dividing the interval into smaller subintervals and calculating the sum of the areas of corresponding rectangles. By practicing a variety of questions, you will develop proficiency in calculating both the upper sums and lower sums.
