What is the Domain Range and Vertical Asymptote of Secant

The video tutorial explains how to graph the secant function by first graphing the cosine function. It highlights the importance of vertical asymptotes, which occur at points where the secant function is undefined. The domain of the secant function is all real numbers except where these asymptotes occur, while the range is from negative infinity to -1 and from 1 to infinity. The tutorial provides a step-by-step guide to understanding the domain and range of the secant function.
