Hi,
Example: Maxwell Relation (thermoD)... ([itex]\frac{∂μ}{∂T}[/itex])[itex]_{p,n}[/itex] =  ([itex]\frac{∂S}{∂n}[/itex])[itex]_{T,p}[/itex] what does it mean having those subscript variables outside of the brackets. thanks

They are kept constant in the process. For example, the left side is the change of µ if you change T, but keep p and n constant.

gives an example of the use of this for deriving one of Maxwells relations Have you studied partial differentiation?
