||This article needs more links to other articles to help integrate it into the encyclopedia. (February 2014)|
In mathematics, two-center bipolar coordinates is a coordinate system, based on two coordinates which give distances from two fixed centers, and . This system is very useful in some[which?] scientific applications(e.g. To calculate the electric field of a dipole on a plane).
The transformation to Cartesian coordinates from two-center bipolar coordinates is
where the centers of this coordinate system are at and .
The transformation to polar coordinates from two-center bipolar coordinates is
where is the distance between the poles (coordinate system centers).
