Graphs of Tangent, Cotangent, Secant, and Cosecant

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.
