,Functions of Many Variables — Partial Differentiation, with the rate of change of y with respect to x. However, we saw in section 1.1.2 that in the physical world some property of the system of interest may depend on several variables. For example, the pressure P of a gas depends on the volume V, temperature T and the number of moles of gas n; that isP = f(T,V,n)
