How Can I Apply Thermodynamic Principles to Solve Homework Equations?

[B30W01F]

Homework Statement

I need to prove the following equation:

Homework Equations

The 4 maxwell relations and their derivations:
https://en.wikipedia.org/wiki/Maxwell_relations

The Attempt at a Solution

I started out with the fundamental equations of
dU=TdS - PdV
and as dS=0, and Cv=(dU/dT)v;
I simplified this to:
dT= -P(dV/Cv)

I did a similar procedure, only this time using the definition of enthalpy to get to
dT = V(dP/Cp)

But I don't know how to proceed from here. I've tried looking at the relations but i don't know what I am missing or if I'm going about this totally wrong...

Thanks in Advance
Cheers

The Maxwell relations are not needed to solve this problem.

You can solve this problem by working with the following equations:
$$dS=\left(\frac{\partial S}{\partial P}\right)_VdP+\left(\frac{\partial S}{\partial V}\right)_PdV\tag{1}$$
$$dS=\left(\frac{\partial S}{\partial T}\right)_PdT+\left(\frac{\partial S}{\partial P}\right)_TdP\tag{2}$$
$$dS=\left(\frac{\partial S}{\partial T}\right)_VdT+\left(\frac{\partial S}{\partial V}\right)_TdV\tag{3}$$
$$dT=\left(\frac{\partial T}{\partial V}\right)_PdV+\left(\frac{\partial T}{\partial P}\right)_VdP\tag{4}$$
