Example 1 from Algebra and Trigonometry, 9.1 Verifying Trigonometric Identities and Using Trigonometric Identities to Simplify Trigonometric Expressions

Graphing the Equations of an Identity

Graph both sides of the identity $\cot θ = \frac{1}{\tan θ} .$ In other words, on the graphing calculator, graph $y = \cot θ$ and $y = \frac{1}{\tan θ} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
See Figure 4.
