Core Concepts of Trigonometric Functions Visualization

This example demonstrates the geometric representation of trigonometric function concepts using points, rays and circles. Core math concepts include trigonometric definitions, similarity transformations, equilateral triangles and 2D vector operations. Construction relies on GeoGebra commands Point, Intersect, Ray, Circle, OrthogonalLine, Segment and Vector to generate intersections, orthogonal lines and vector objects linking function graphs with geometry. Suitable for high school math instruction and self-study to connect trigonometry with visual constructions.
