Where does the secant graph come from?

The video tutorial explains how to graph the secant function by understanding its relationship with the cosine function. It begins with a review of the cosine graph, highlighting key points and their significance. The tutorial then demonstrates how to graph the secant function by using the reciprocal of cosine values, identifying asymptotes, and plotting shared points. The instructor emphasizes the concept of secant as a 'flipped' version of cosine and suggests using graphing technology for verification.
