Conversion from rectangular coordinates to polar co-ordinates :

\

If $\"\"$ is a point with rectangular coordinates $\"\"$ , the polar coordinates $\"\"$ of $\"\"$ are given by $\"\"$ and $\"\"$

\

$\"\"$

\

The point is $\"\"$

\

Conversion to polar coordinates :

\

Substitute $\"\"$ and $\"\"$ in $\"\"$ .
