Explanation For x2 y2 = 2xy, we get (by differentiating implicitly), dy dx = 1 That's the same as the derivative of a linear function with slope, 1 Hmmmmm Let's see and dy dx = 1 (Which we already knew by differentiating, but this may be of interest as well) (del)/(del x)(x^2y^2)=2xy^2 because y^2 is constant relative to x and (del)/(del y)(x^2y^2)=2x^xy because x^2 is constant relative to y Calculus ScienceF((x1,y1),(x2,y2)) = 2x1x2 x1y2 x2y1 and q(x,y) = 2x2 2xy = f((x,y),(x,y)) Let u = (x1,y1),v = (x2,y2) and let us calculate 1 2 (q(uv)−q(u)−q(v)) = 1 2 (2(x1x2) 22(x 1x2)(y1y2)−x 2 1−2x1y1−2x 2 2−2x1y2) = 1 2 (4x1x2 2(x1y2 x2y1)) = f((x1,y1),(x2,y2)) If A = (a i,j) is a symmetric matrix, then the corresponding form is f(x
