Moving Point and Function Graph Dynamic Demo

This example demonstrates the dynamic changes of a function graph as a moving point travels along the boundary of a rectangle and connects to a fixed point. Core math concepts include function graphs, locus of moving points, geometric transformations, and matrix transformations. Construction highlights: utilizes Polygon to build the rectangle, Locus to generate the trajectory, If for conditional logic, Area for calculation, and Square1. Suitable for high school or pre-university students to visually understand the interaction between moving points and geometric figures.
