    You need to say what all those variables represent, and what equation(s) you have from which you wish to derive this one. What is the actual full question you are trying to answer?

    This sounds like a homework problem. Is it?

    That is the problem. My lecturer asked me to derive the equation given without any details.

    More like it but it is an assignment for us. My lecturer just gave us that equation and asked to derive the equation without any details.

    *UPDATE*

    The question are asking how to prove the left equation equal to the right equation

    What is dU in terms of dS and dV? If we represent the entropy S as S(T,P), what is dS in terms of the partial derivatives of S with respect to T , P, and dT and dP?
