The differential of a multivariable function is given by. d z = ∂ z ∂ x d x + ∂ z ∂ y d y dz=\frac {\partial {z}} {\partial {x}}\ dx+\frac {\partial {z}} {\partial {y}}\ dy d z = ∂ x ∂ z d x + ∂ y ∂ z d y. ∂ z ∂ x \frac {\partial {z}} {\partial {x}} ∂ x ∂ z is the partial derivative of f f f with respect to x x x.
