Key Concepts

Right Endpoint Evaluation

Using right endpoints means that the function is evaluated at the rightmost point of each subinterval of the partition. This specific choice of sample point is used to form the sum that approximates the integral, impacting the accuracy of the approximation and is one of several possible sampling strategies.

Limit Process

The limit process involves taking the number of subintervals, n, to infinity, which causes the width of each subinterval, ?x, to approach zero. This process ensures that the Riemann sum converges to the exact value of the definite integral by capturing the cumulative effect of the function’s behavior over the interval.

Riemann Sum

A Riemann sum is a method for approximating the area under a curve by summing the areas of individual shapes, typically rectangles, over subintervals of the domain. This method forms the foundation for defining the definite integral as the limit of such sums as the subintervals become infinitely small.

Partitioning of the Interval

Partitioning an interval refers to dividing the domain of integration into smaller, equally spaced subintervals. The width of each subinterval, denoted by ?x, is calculated by taking the difference between the upper and lower limits of integration and dividing by the number of subintervals, n.
