Trigonometric Functions and Transformations

The video tutorial explains how to analyze and graph the function y = 3 * tangent(2x + π/2). It covers the concepts of period, vertical and horizontal shifts, and how to factor the function for graphing. The tutorial also demonstrates how to graph the transformed tangent function by identifying key points and vertical asymptotes, emphasizing the effect of the coefficient on vertical stretching.
