Subsection10.3.3 Summary. There are four second-order partial derivatives of a function f of two independent variables x and y: fxx = (fx)x, fxy = (fx)y, fyx = (fy)x, and fyy = (fy)y. The unmixed second-order partial derivatives, fxx and fyy, tell us about the concavity of the traces.

Sep 04, 2020 · The good news is that, even though this looks like four second-order partial derivatives, it’s actually only three. That’s because the two second-order partial derivatives in the middle of the third row will always come out to be the same.
