Polar co-ordinates resources
The (x, y) co-ordinates of a point in the plane are called its Cartesian co-ordinates. But there is another way to specify the position of a point, and that is to use polar co-ordinates (r, theta). In this unit we explain how to convert from Cartesian co-ordinates to polar co-ordinates, and back again.
