WebHigher Order Partials. Consider the function f(x,y) =2x2 +4xy−7y2. We’ll start by computing the first order partial derivatives of f , with respect to x and y. fx(x,y) fy(x,y) =6x+4y =4x−14y. We can then compute the second order partial derivatives fxx and fyy by differentiating with respect to x again, and with respect to y again.
