Khan Academy: Pre Calculus: Polar Coordinates 2

The sequel to Polar Coordinates 1 from the Khan Academy, this segment goes through some examples on converting polar coordinates to rectangular coordinates and converting a Cartesian equation to a polar equation. Graphing is also used to illustrate that polar coordinates/equations are just another way to name the same rectangular coordinates/equations. This video is also included in the Trigonometry strand.
