Polar Coordinates
Procedure for Converting Coordinates
A point with polar coordinates has Cartesian coordinates (x,y) where
and
A point with Cartesian coordinates (x,y) has polar coordinates , where

Symmetry in Polar Equations
Symmetry about the x- axis occurs if the point is on the graph whenever is on the graph
Symmetry about the y- axis occurs if the point is on the graph whenever is on the graph
Symmetry about the origin occurs if the point is on the graph whenever is on the graph
