Polar form to Cartesian form

Adjust the distance of point P from the Pole by changing the radial distance r. Adjust the angle of  point P with respect to the Polar Axis (i.e positive x-axis) . Notice the how you can use trigonometry to find Cartesian co-ordinates of point P. You can turn on the Cartesian grid to help visualise the relationship between Polar and Cartesian co-ordinates.
