Definition

∆x represents the width of each subinterval in a Riemann sum. It is the change in x-values between consecutive sample points.

Sample Points: These are specific x-values chosen within each subinterval to approximate the function's behavior.

Partition: A partition is a collection of subintervals formed by dividing the interval over which we are integrating into smaller pieces.

Riemann Sum:

A Riemann sum is an approximation method for finding the area under curves by dividing it into multiple rectangles and adding their areas.
