'''Polar coordinate systems''' are coordinate systems in which a point is identified by a distance from some fixed feature in space and one or more subtended ]. |

<i>Circular Polar Coordinates</i> |
|

|
|
|
|
|
|
A two-dimensional coordinate system in which a point is located by its distance from some predefined point (known as the origin) and the angle made by a line joining from the origin to the point and some fixed axis. The angle is typically denoted θ and the distance '<i>r</i>' (for radius). |

<i>Cylindrical Polar Coordinates</i> |
|
|
|
|
|
|
|
|
|
|
|
A three-dimensional system similar to circular polar coordinates except the angle and radius are measured relative to a fixed straight axis in space, and a third co-ordinate is used, which measures the vertical height above some fixed plane normal to this axis. |
