If I have homogenuous function [tex]f(x,y,z,...)[/tex] of degree [tex]r[/tex] than:
[tex]x\frac{\partial f}{\partial x}+y\frac{\partial f}{\partial y}+...=rf[/tex]
In thermodynamics:
[tex]dU=TdS-pdV+\mu dN[/tex]
If I said U is homogenuous function of degree 1 I will get
[tex]U=TS-pV+\mu N[/tex]
When can I use this assumption?
