Area Under Curve

This example demonstrates how to explore the definite integral of a function using GeoGebra, focusing on the area under the function graph. Key math concepts include definite integral, function graph, and integral calculation. Construction highlights involve using commands like Point and Integral with objects such as function f, interval endpoints a and b, integral area A, and text annotation text1. Suitable for high school students and above to learn and understand definite integrals in calculus, or for teaching demonstrations.
