Parametric Equations 4, Parametric Equations and Polar Coordinates, Precalculus

In a follow-up to the problem presented in the last video, Sal considers whether other parametric equations move along the same path as the last equations. He shows that taking a multiple of time changes the speed of the position along the graph's path. Continuing with this insight, Sal shows how an unlimited number of parametric equations can be built from an equation.
