Unit Circle & Periodic Functions (Geogebra)

This is a Geogebra program for teaching students the unit circle. The program has been designed using Geogebra 5.0 (download version). This resource is valuable for use when teaching trigonometry, radians and the graphs of sine, cosine and tangent.

The program can also be used to show students how frequency and phase relate back to the unit circle and periodic functions. The program allows you to quickly enter specific angles of rotation for use when teaching students exact ratios. The program will even draw the sine, cosine and tangent graphs as the point rotates around the unit circle.

This is a visually engaging teaching tool that will help students to better comprehend how the unit circle connects with periodic functions.
