Key Concepts

Riemann Sum

A Riemann sum is a method for approximating the definite integral of a function over a given interval by dividing the interval into subintervals, evaluating the function at selected sample points within these subintervals, and then summing the products of these function values and the corresponding subinterval widths. This approach forms the conceptual basis for integration in calculus.

Partitioning an Interval

Partitioning an interval involves dividing it into smaller subintervals, which can be of equal or varying lengths. The subdivision allows complex areas under a curve to be approximated by simpler shapes, and when the subintervals are of equal length, the width (often denoted as delta x) is determined by dividing the length of the entire interval by the number of subintervals.

Sample Point Selection

Sample point selection refers to the process of choosing specific points within each subinterval where the function is evaluated. The accuracy of the Riemann sum approximation can depend on the choice of these points, whether they are the left endpoints, right endpoints, midpoints, or any arbitrarily chosen points within the subintervals.

Function Evaluation

Function evaluation in the context of Riemann sums involves calculating the value of the function at the chosen sample points. These values are subsequently multiplied by the subinterval widths to estimate the area under the curve, thereby approximating the definite integral of the function.
