SUMMARY
The discussion centers on the derivation of the relationship cp/cv = kt/ks in thermodynamics, specifically through the manipulation of Maxwell's relations. The user presents their equation cp/cv = (dS/dP)T(dP/dT)S / (dS/dV)T(dV/dT)S, which they believe can be transformed into an alternative form. However, the textbook provides a different expression: (dS/dP)T(dV/dS)T / (dV/dT)S(dT/dP)S. The confusion arises from the application of the reciprocal relationship 1/(dX/dY)_Z = (dY/dX)_Z.
