Definite Integral Exploration 3

This example demonstrates the geometric interpretation of definite integrals over a given interval, specifically the area enclosed by a function's graph and the x-axis. Core mathematical concepts include definite integrals, trigonometry, distributions, piecewise functions, numbers, and random variables. It is constructed using GeoGebra commands/objects like Point, Integral, parameters a and b, function f, and text elements. Suitable for high school and above students to visualize and understand definite integrals with parameter adjustments.
