Graphs of Tangent, Cotangent, Secant, and Cosecant

Published on 10/17/2008

Activity Overview

The goal of this activity is for students to see how the graphs of tangent, cotangent, secant, and cosecant are generated and related to the unit circle. A point is animated around the unit circle as data points are captured to create a scatter plot. Students discover a way to relate each of these trigonometric functions to sine and cosine.
