Cartesian coordinate system
Cartesian coordinates, which are the signed distances from the point to three mutually perpendicular planes. More generally, n Cartesian coordinates specify...
Coordinate system
same meaning as in Cartesian coordinates is added to the r and θ polar coordinates giving a triple (r, θ, z). Spherical coordinates take this a step further...
Spherical coordinate system
sphere that is described in Cartesian coordinates with the equation x2 + y2 + z2 = c2 can be described in spherical coordinates by the simple equation r...

Circumcircle
give explicitly an equation of the circumcircle in terms of the Cartesian coordinates of the vertices of the inscribed triangle. Suppose that A = ( A...
Homogeneous coordinates

Barycentric coordinate system
coordinates are strongly related with Cartesian coordinates and, more generally, to affine coordinates (). Barycentric coordinates are particularly useful in triangle...
Cylindrical coordinate system
between cylindrical and Cartesian coordinates, it is convenient to assume that the reference plane of the former is the Cartesian xy-plane (with equation...
Divergence

Curvilinear coordinates
lines may be curved. These coordinates may be derived from a set of Cartesian coordinates by using a transformation that is locally invertible (a one-to-one...
