Polar coordinates are (r,. θ. ) coordinates – where . θ. is the directed angle measured in the usual way and r is the directed distance from the origin to the point in question. “Directed distance” means that we travel in the direction of the terminal side of .

Some processes and equations involving the Cartesian system can become very complicated. You can simplify some of these by using Polar coordinates instead. . Your GPS Coordinates. www.sodblitz.org.
