Graphing Trigonometric Functions on TI-84

This video tutorial demonstrates how to graph sine, cosine, and tangent functions using a TI-84 graphing calculator. It covers setting up the calculator in both degree and radian modes, adjusting window settings, and interpreting the graphs. The tutorial also explains how to generate tables of values and addresses the handling of errors in tangent graphs due to vertical asymptotes.

What is the primary goal of the lesson on graphing trigonometric functions using the TI-84 calculator?

• To understand the history of trigonometry

• To graph y = cosine x and generate tables in degree and radian modes

• To explore advanced calculus concepts

• To learn how to solve trigonometric equations
