**Definition of Parametric Equations**parametric equation is a method of defining a relation using parameters. A simple kinematic1 example is when one uses a time parameter to determine the position, velocity, and other information about a body in motion. 1. Kinematic.The branch of mechanics that studies the motion of a body or a system of bodies without consideration given to its mass or the forces acting on it. http://en.wikipedia.org/wiki/Parametric_equation**We will not be finding parametric equations, in this**example. In this class we will graph parametric equation also eliminating the parameter.
