This example dynamically demonstrates the relationship between points on the unit circle and angles, visually showing the definitions of trigonometric functions. Core concepts include the unit circle, angles, and trigonometric functions (sine, cosine, tangent). Construction highlights involve using GeoGebra commands like Segment, Point, and Angle to build the unit circle, angle markings, and trigonometric function lines. Suitable for high school mathematics teaching to help students understand the geometric meaning of trigonometric functions and the application of the unit circle.
