Category:Polar Coordinates

This category contains results about Polar Coordinates.
Definitions specific to this category can be found in Definitions/Polar Coordinates.

Let $P$ be any point different from $O$.

Let a straight line $OP$ be drawn from $O$ to $P$.

Radial Coordinate

The length of $OP$ is called the radial coordinate of $P$, and usually labelled $r$.

Angular Coordinate

The angle measured anticlockwise from the polar axis to $OP$ is called the angular coordinate of $P$, and usually labelled $\theta$.

If the angle is measured clockwise from the polar axis to $OP$, its value is considered negative.
