Thread: Another exact equation prob.

Determine whether the equation is exact. If it is exact, then solve the equation.



My books answer key says that this equation is exact, but I don't see how. Your and your .

So taking the partial derivative and .

I am pretty sure this is correct, so how is it possible that the equation is exact if the two partial derivatives are not equal?
