Everything You'll Have Covered

In the Activity Object, a different procedure is given to graph a tangent function. Now, we will graph the tangent function using the transformations for a function.

First, recall that the function has domain all real numbers x except , where n is an odd integer and range all real numbers. At the values , there are vertical asymptotes. The period of is
