Parametric equations can be used to graph relations that are functions as well as relations that are not functions. For this reason parametric equations can be a useful tool in understanding trigonometric functions and inverse trigonometric functions. In this module you will learn to graph parametric equations on your calculator and then study trigonometric functions and their inverses.
