Graph the Secant Function with a Phase Shift of pi Halves

The video tutorial explains how to graph the secant function by first graphing its reciprocal, the cosine function. It covers the basic trigonometric information needed, such as amplitude, period, and shifts. The tutorial then demonstrates how to graph the cosine function, set up the graph scale, and finally relate the secant graph to the cosine graph by identifying asymptotes and maximum/minimum points.

What is the first step in graphing the secant function?

How do you determine the amplitude of the cosine function?

What is the formula for the period of a trigonometric function?

Explain how to find the horizontal shift in the cosine function.

What happens to the secant function when the cosine function equals zero?

Describe the relationship between the maximum and minimum points of the cosine and secant functions.

How do you graph the secant function based on the cosine function?
