I'm reading Kittel&kroemer's Thermal physics. How can I know Entropy's functional dependency?

Author assume entropy's functional dependecy without explanations and derive some equaltities. So I can't follow it.

N the number of particles. U Energy of the system. V. volume of the system [itex]\tau[/itex] fundamental temperature

[itex]\sigma(N,U)[/itex], [itex]\sigma(\tau,V) etc...[/itex]

2. Relevant equations

3. The attempt at a solution
