1. The problem statement, all variables and given/known data Is (x2 -y)dx + xdy = dF an exact differential ? dF = path dependant ( i.e. d has a line strikethrough it as h in planck's constant.) 2. Relevant equations (x2 -y)dx + xdy = dF 3. The attempt at a solution I don't know what exact and inexact differentials are. Please help me.
