Learn to find the range of the secant function

The video tutorial covers graphing the secant function y = 2 sec(3x + π/2). It begins with setting up the problem and understanding reciprocal functions. The instructor explains how to calculate the period and X scale, determine the phase shift, and sketch the graph. The tutorial emphasizes the importance of graphing the cosine function first to aid in graphing the secant function. It concludes with analyzing the graph's properties, including amplitude, period, phase shift, and range.
