***Many equations which are simple in Cartesian coordinates are very complicated in polar coordinates, and vice versa. To solve any particular problem, one system may be much more tractable than the other. The ability to convert from one to the other quite readily allows us to try both, then use only the easier one.

The 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 angles. They are the most common systems of curvilinear coordinates.

The term polar coordinates often refers to circular coordinates [two-dimensional.] Other commonly used polar coordinates are cylindrical coordinates and spherical coordinates [both three-dimensional.]
