Cosecant Function
The last two trigonometric functions you will learn how to graph are the cosecant and secant functions. Since the cosecant and secant functions are the reciprocals of sine and cosine, those two functions have also been included in the respective graphs as references.
The following is the graph of f(x) = csc(x):
