WebNov 4, 2007 · Now that we know that fx= 2x+ 3y f (x,y) must equal x^2+ 3xy+ h (y). Then we would have fy= 2x+ h' and fyy= h"= 2 so h, since it is function of y only, is y^2+ cy+ d. Taking those constants of integration to be 0 for simplicity, f (x,y)= x^2+ 3xy+ y^2. That has fxx= fyy= 2> 0 but fxy= 3 so D= fxxfyy- (fxy)^2= 4- 9= -5.

We also can see that xx means: it is positive if the surface is bent concave up in the x direction and negative if it is bent concave down in the x direction.

WebThe chain rule of partial derivatives is a technique for calculating the partial derivative of a composite function. It states that if f (x,y) and g (x,y) are both differentiable functions, and y is a function of x (i.e. y = h (x)), then: ∂f/∂x = ∂f/∂y * ∂y/∂x.
