Learn the Easiest Way to Graph the Secant Function with a Change in the Period

The video tutorial explains how to graph the function Y = secant(πX) by first graphing its reciprocal, the cosine function. It covers the transformation form for trigonometric functions, focusing on amplitude, period, phase shift, and vertical transformation. The tutorial provides a step-by-step guide to graphing the cosine function, including setting up the X scale and identifying key points. It then transitions to graphing the secant function by identifying asymptotes and using the cosine graph to plot the secant graph accurately.

Describe the process of graphing the cosine function based on its key points.

What happens to the secant graph at the points where the cosine graph equals zero?

How do you identify the asymptotes in the secant graph?
