Curated and Reviewed by Lesson Planet

Following his intuitive manner, Sal considers another set of parametric equations. This time, he looks at two equations using trigonometric functions and, using one of the basic trigonometric identities, removes the parameter from the equations by rewriting them as the equation of the ellipse. Using prior knowledge of graphing conic sections, he graphs the ellipse and shows how one can see how the position at time t can be plotted along the path of the graph.
