What is the difference between an exact and and inexact differential?(adsbygoogle = window.adsbygoogle || []).push({});

These were introduced in my physics 2 book with the first law of thermodynamics represented by differentials,

dEint= dQ + dW

Then, it has a note that says

"Note that dQ and dW are not true differential quantities because Q and W are not state variables; however dEint is. Because dQ and dW are inexact differentials, they are often represented by the symbols dQ and dW,both with lines through the vertical part of the d's. Sorry, I it wouldn't let me open the latex instructions.

Thanks- Erik
