[Curvilinear coordinates]
If we have functions x = f ( u , v ) and y = g ( u , v ) such that the pair of real numbers ( x , y ) and the pair of real numbers ( u , v ) correspond one-to-one, then we can take the coordinates of point P on a plane whose orthogonal coordinates are ( x , y ), and take ( u , v ) to correspond to ( x , y ). ( u , v ) are called the curvilinear coordinates of P. …
