A simple way of deriving the equation is by a
second order Taylor series expansion of the extrapolation
wavenumber relative to and :

If we plug equation (20) into equation (21), we obtain
an equivalent form for the equation in a
semi-orthogonal 3-D Riemannian space:

For the particular case of Cartesian coordinates
(),

(23) |
which is the usual form of the equation.
