Sum vs. Integration Riemann sums and definite integrals are two ways of finding the accumulated value of a function, but they differ in precision and interpretation. A Riemann sum approximates the area under a curve by dividing the interval into a finite number of rectangles and adding their areas together. Depending on whether the left endpoint, right endpoint, or midpoint is chosen for each rectangle’s height, the estimate may be an overestimate or an underestimate. With only a few rectangles, the approximation can be quite rough, but increasing the number of rectangles makes the estimate progressively more accurate. A definite integral is the exact value obtained by taking the limit of these Riemann sums as the widths of the rectangles approach zero. In this limit, the rectangles become infinitely thin, eliminating the approximation error and producing the true accumulated area under the curve. This relationship shows that integration is not a completely separate idea from Riemann sums—instead, a definite integral is the limit of increasingly refined Riemann sums, providing the foundation for much of integral calculus. #math #integral #algebra #calculus
