What is the Domain Range and Vertical Asymptote of Tangent

The video tutorial explains how to evaluate the domain and range of the tangent function. It begins with a rough sketch of the tangent graph, highlighting its cyclical nature and key features such as intercepts and asymptotes. The domain is identified as all real numbers except where vertical asymptotes occur, which are spaced π units apart. The range is described as all real numbers, as the graph extends infinitely in both positive and negative directions.
