Web3 Answers Sorted by: 1 The red one is correct (except that you forgot the constant of integration), since it can be written as df = d(x + y + z), which means that f(x, y, z) = x + y + z + C. But the green one is wrong, since the orange one is not (in general) the same thing as df = d(∂f ∂x + ∂f ∂y + ∂f ∂z).
