Exploration of the Trigonometric Identities using the Unit Circle

Published on 11/04/2008

Activity Overview

Students will investigate the relationship of the trigonometric functions to similar triangles created using the unit circle.

Before the Activity

The teacher should work through the activity before presenting the activity in class. Also, students must be familiar with the trigonometric functions prior to the activity. The discussions during the activity should be completed together as a class.

During the Activity

The teacher should walk around the room to observe student progress. Students should stop at discussion questions for a whole class discussion.

After the Activity

The teacher should wrap-up the activity by asking students to identify what they learned from the activity and the questions that they still have after the activity.
