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.
