This example demonstrates how to calculate the six trigonometric functions of an angle drawn in standard position using a point on its terminal ray. Key math concepts include trigonometric definitions, right triangles, unit circle, and vectors. GeoGebra commands like Segment, Ray, Point, Angle, Vector, and Intersect are used to construct the necessary geometric elements. Suitable for high school mathematics education to understand and apply trigonometric function definitions and calculations.

AI Drawing Prompt Reference

Draw a terminal ray from point P in the coordinate plane, and let it intersect the positive x-axis at point A. Construct angle α. Take another point B on the terminal ray, and construct vectors u from the origin to point B, v from B to P, and w from P to another point C on the terminal ray. Calculate and display the sine, cosine, tangent, cosecant, secant, and cotangent values of point P.
