Function and Geometry Relationship Demo

This example dynamically demonstrates the relationship between function graphs and geometric figures (like similar triangles, angle columns), revealing the connection between functional properties and geometric properties. Core math concepts include functions, similar triangles, cosine theorem, angle columns, congruence, integration, etc. Construction highlights involve using GeoGebra commands to construct objects a, b, c, f, g for dynamic interaction between function graphs and geometric shapes. Suitable for high school and above learners to understand the integrated application of functions and geometry.
