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 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?
