Now, the partial derivative terms are not 0. The way to consider the covariance term is to view it as stating that dzdδ=βdt. First, dw with respect to dt. As always, dw/dt is an order larger than dw/dδ. Thus, we get the s2α2/2 (square it to make the correct order—dδ2. The same method works for the dy/dz term: from this comes the σ2/2.

2. Higher order partial derivatives. We can apply the partial derivative multiple times on a scalar function or vector. For example, given a multivariable function, , there are four possible second order partial derivatives: The last two partial derivatives, and are called “mixed derivatives.” An important theorem of multi-variable calculus is
