Dynamic Trigonometric Functions: Rotation and Intersection Construction

This GeoGebra example dynamically demonstrates the geometric relationship between a rotated triangle and the intersection points on trigonometric function graphs. Core mathematical concepts include trigonometric functions, rotational transformations, the Pythagorean theorem, and circumcircles. Construction highlights: uses Segment to draw line segments, Rotate for transformation, and Intersect to find crossing points, involving objects c, f, k, f', A, B, C, D. Ideal for high school or pre-calculus students to visually grasp the connection between trigonometric graphs and geometric transformations.
