What is the Domain Range and Vertical Asymptote of Cotangent

The video tutorial explains how to graph the cotangent function, focusing on its domain and range. It begins by setting up the axes and identifying vertical asymptotes at multiples of π. The domain is defined as all real numbers except where X equals π + πN, where N is an integer. The range is all real numbers, as the graph extends infinitely in both vertical directions. The tutorial emphasizes understanding the behavior of the cotangent function and its repeating pattern.
