## Main Question or Discussion Point

I'm looking at one step in my thermodynamics book and they go from

[tex] pV = \nu*R*T [/tex]

to

[tex] p*dV + V*dp = \nu * R * dT[/tex]

I think there's an application of the chain rule in here but I don't see exactly how it's working. Could someone show me the steps in between?

Thanks!
