This example demonstrates geometric transformations such as rotation, dilation, and intersection of points, lines, and circles through animation, combined with dynamic changes in function and trigonometric function graphs. Core mathematical concepts include angles, straight lines, matrix transformations, function graphs, cones, trigonometric functions, and the unit circle. Construction highlights the use of commands like Point, Rotate, Angle, Line, Circle, Intersect, CircleSector, Dilate, Vector, Midpoint, Segment, Ray, and CircleArc in GeoGebra. Suitable for high school and above students to understand the dynamic relationship between geometric transformations and function graphs, as well as practical applications.
