Directional Derivatives and the Gradient Vector Suppose that f; (0,1) = 3 and f, (0,1) = 2. From the point (0,1), in what direction should you travel to increase the value of f(x, y) as quickly as possible? (Hint: v · u = |v||u| cos(8) has its largest value when 8, the angle between vectors v and u, is 0.)
