f(x, y, z, w) = a cosz+acosy+acosz+acos w+zy+yz+zw which is a function of four variables, and it has a critical point at x=y=z=w = 0 (this is obvious; you do not need to verify it). (A) Classify the critical point, assuming a = 0. (B) Classify the critical point, assuming a = 1/2. (C) Classify the critical point, assuming a = 1.
