Definition

coordinate system

a coordinate system is a system which uses one or more numbers, or coordinates, to uniquely determine the position of a point or other geometric element on a manifold such as Euclidean space.(Wikipedia)

coordinate change

A coordinate change is a set of functions fr(x1,...,xN) (r=1,...,N).

One generally supposes that J=|xrxs| does not vanish.

The new coordinates of a point (x1,...,xN) are (x1,...,xN) where xr=fr(x1,...,xN) (r=1,...,N).
