Graphing the Secant Function with a Horizontal Shift

The video tutorial explains how to graph reciprocal trigonometric functions, focusing on secant as the reciprocal of cosine. It covers the steps to graph the cosine function, including determining amplitude, period, and X scale. The tutorial also discusses vertical translation and how to use the cosine graph to aid in graphing the secant function. Key points include creating vertical asymptotes at X intercepts and finalizing the secant graph by removing the cosine graph used as an aid.

What effect does a vertical translation have on the graph of the cosine function?

How does the graph of the secant function behave at the X intercepts of the cosine function?

Describe the process of creating vertical asymptotes when graphing the secant function.
