Unit Circle Showing the 6 Trig Functions

This GeoGebra example visualizes all six trigonometric functions—sine, cosine, tangent, cotangent, secant, and cosecant—on the unit circle, dynamically linking each function's value to the angle as a point moves around the circle. It demonstrates the unit circle definition of trigonometric functions, the ratios of sides in right triangles, and the periodic nature of these functions. The construction uses GeoGebra commands such as Intersect, Circle, Point, Segment, Tangent, OrthogonalLine, Angle, and LaTeX text objects to create a rich diagram with radius, perpendicular segments, tangents, and angle labels. This resource is ideal for high school or introductory college students learning trigonometry, as well as for teachers demonstrating the geometric origins of trigonometric ratios in an interactive classroom setting.
