How to Sketch a Graph Given Parametric Equations with the orientation indicated on the graph. Also learn how to eliminate the parameter and write the 2 parametric equations as a single equation with 2 variables. We discuss 3 examples in this video. The first example is a line, the second is a parabola, and the third is an ellipse. We also go over how to use substitution as well as the pythagorean trig identity to eliminate the parameter in the third example. We make use of tables as well as rewriting the equations.
