Unit Circle and Trigonometric Functions by Michael PArk (2)

This example demonstrates the properties of trigonometric functions using a unit circle. It shows the periodicity, symmetry, and the relationship between points on the unit circle and trigonometric function values. By constructing arcs and points, the dynamic changes in angle and their effects on trigonometric function values can be observed. The example uses Circle, Point, CircleArc commands in GeoGebra. Suitable for high school mathematics education and students learning trigonometric functions.
