WebIf z = f(x, y) is a function in two variables, then it can have four second-order partial derivatives, namely ∂ 2 f / ∂x 2, ∂ 2 f / ∂y 2, ∂ 2 f / ∂x ∂y and ∂ 2 f / ∂y ∂ x . To find them, we can first differentiate the function partially with the latter variable, and then partially differentiate the result with respect to the ...
