Inexact Differential

#Physics #Math

$\displaystyle \mathrm{d}\kern{-4.3pt}\bar{\small\phantom{q}}$

• The inexact differential of a quantity is used when that quantity's integral is path dependent
  • E.g.: Heat is path dependent, so $\displaystyle \mathrm{d}\kern{-4.3pt}\bar{\small\phantom{q}}Q$ is used
