Compute the second partial derivatives
∂2f/∂x2, ∂2f/∂x ∂y, ∂2f/∂y ∂x, ∂2f/∂y2
for the following function.
f(x, y) = log(x-y),
on the region where
(x, y) ≠ (0, 0)
verify the following theorem in this case.
if f(x, y) is of class c2 (is twice continuously differentiable), then the mixed partial derivatives are equal; that is,
∂^2f/∂x ∂y = ∂2f/∂y ∂x.
a) ∂2f/∂x2,
b) ∂2f/∂x ∂y,
c) ∂2f/∂y ∂x,
d) ∂2f/∂y2
