Riemann Sum | Definition, Formula & Examples

Riemann sums in summation notation

@gamma.mathematica on Instagram: "Riemann sums and integrals both aim to calculate the area under a curve, but they differ in precision and method. A Riemann sum is an approximation, where the area is estimated by summing the areas of rectangles under the curve. The width of each rectangle is based on a partition of the interval, and the height is taken from the function’s value at a chosen point within each subinterval (like the left endpoint, right endpoint, or midpoint). As the number of rect
