This applet focuses on the conversion between rectangular and polar coordinates.
Even without formal knowledge about polar coordinates, we can still ask how the direction and distance of a point from origin could be related to the usual coordinates, with a useful definition of sine and cosine values.
When you hide some of the values on the left, you can practise your estimation.
