Geometric Properties of Trigonometric Functions

2015-09-14 04:59
This applet illustrates the properties of trigonometric functions via dynamic geometric constructions. Using a unit circle, vectors, and angles, it builds trigonometric lines to show their geometric definitions. Dynamic rotation helps users understand periodicity, symmetry, and sign changes across quadrants. Ideal for high school math teaching.
