Jacobian for multi-variable

  1. Jun 4, 2010 #1
    Hi,

    Assume that I have f(u,v,w,h) du dv dw dh and I need only to change three variables (u, v, w) say to other variables called (s, r, t) and keep h as is it is

    So my question can I write this as

    f(u,v,w,h) du dv dw dh = G(r,s,t,h) J(r,s,t) dr ds dt dh

    where J is jacobian transformation. What is the condition that has to be satisfied?

    You can always do it (as long as the transformation is nice). If you want to be completely consistent, let h' (new) = h (old) so you will be working with a four variable transformation.
