Brett shows you how to graph the Cosecant (0:50), Secant (9:17), and Cotangent (14:05) graphs by hand without a calculator. You will learn about vertical asymptotes as well as how using sine, cosine and the reciprocal identities can help you easily graph the cosecant and secant graphs. Finally, we'll take a small dive into the unit circle to help us graph the cotangent function.
