Area Between Two Curves by Betty Voon Wan Niu

This example demonstrates how to calculate the area between two functions, f and g. It illustrates the change in the sign of the integral when the upper and lower limits are adjusted. Key math concepts include definite integrals and integral calculus. The construction uses GeoGebra commands IntegralBetween and Intersect to find intersections and compute the area, involving objects like f, a, b, g, Area, A, B. Suitable for high school and above students learning calculus.
