Area Between Curves with Riemann Sums

① This GeoGebra example visualizes the area enclosed between two function curves using dynamic Riemann sums, updating the approximate area as parameters change. ② Core mathematical concepts include definite integrals, Riemann sums, area between curves, and the limiting process where finer partitions yield more accurate approximations. ③ Construction details: uses Function to define f and g, Segment to partition the interval, Sequence to generate rectangles, and IntegralBetween to compute the exact area; sliders a, b control the integration interval, slider n controls the number of subintervals, with lists list1 and list2 storing rectangle vertices and text objects displaying values. ④ Ideal for high school or early college calculus students to grasp the geometric meaning of integration and numerical approximation, and for teachers as an interactive demonstration tool.
