Hi all.
How would I express and manipulate in Maxima, equations with exact
differentials as commonly done in thermodynamics eg, go from this equation
to the next
delta U delta U
U = ------- S + ------- V + ...
delta S delta V
delta U delta U
dU = ------- dS + ------- dV +.....
delta S delta V
Also, partial derivatives while tracking the variables held constant eg in
Maxwell's equation:
delta S | delta P |
------- | = ------- |
delta V | T delta T | V
Cheers
