Parametric Equations

In Parametric equations, the goal is to sketch the graph and eliminate the parameter. The equation given tells where the starting point of the graph and the direction in which the graph is heading toward. When solving these problems, you need to eliminate the t value by substitution and elimination. When graphing you need to plug in the points for t to find where you are going to display them on the graph. Once you sketch the graph and eliminate the parameter "t", you already know how to solve parametric equations.
