Integral Area Function Demonstration

This example demonstrates calculating the area between a function's graph and the x-axis using definite integrals. Core math concepts include integral calculus, area computation, and function graphing. It utilizes GeoGebra commands like Integral and Textfield, along with objects such as f, a, b, g, InputBox1, InputBox2 for interactive visualization. Suitable for high school and above students studying calculus and analytical geometry to understand the geometric application of integrals.
