What are polar co-ordinates?

polar co-ordinates uses a radius and a degree to represent a point. point (r,w) in polar co-ordinates is (r*cosw,r*sinw) in X-Y co-ordinates.

Cartesian coordinates are based on X - Y graph values. Polar coordinates are based on angle and distance. So where Cartesian coordinates will specify (1,1) the polar coordinates will be 45 degrees, the square root of two (the distance between the origin, (0,0) and the point at (1,1) using Cartesian coordinates)

Aww man I used to know this! Lol hopefully it will come back to me!

This is a typical comment-fishing discussion topic, I assume. If you are really to know it, look it up on wikipedia

Yes it is part of mathematics and it is called co-ordinate geometry or analytical geometry.
