Hi,(adsbygoogle = window.adsbygoogle || []).push({});

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?
