mathswithmuza on Instagram: "Riemann sums and integration are both methods used to calculate the area under a curve, but they represent different stages of the same idea. A Riemann sum is an approximation: you divide the interval into smaller subintervals, draw rectangles (or other simple shapes) that touch the curve in a chosen way (left endpoints, right endpoints, or midpoints), and then add up the areas of these rectangles. The accuracy of this method depends on how many rectangles you use an
