Trigonometric Functions Illustrated on the Unit Circle

This GeoGebra example visually displays the magnitudes of the six trigonometric functions (sine, cosine, tangent, cotangent, secant, cosecant) on the unit circle. Core concepts include trigonometric definitions, the unit circle, Pythagorean theorem, and angle-function relationships. Construction uses Circle to draw the unit circle, Point and Segment for key elements, OrthogonalLine and Intersect for perpendiculars, RotateText and Vector for labels, plus Angle, Polygon, and TableText for angles and value tables. Ideal for high school trigonometry lessons or self-study to connect abstract functions with geometry.
