How to graph the secant graph

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 critical points and their cyclical nature. The instructor demonstrates how to create a table of cosine values and uses these to graph the secant function, emphasizing the role of asymptotes. The tutorial concludes by finalizing the secant graph, using the cosine graph as a reference.
