Chapter 14, Problem 43

(choose chapter or problem)

(a) The surface S is given, for some constant a, byz = 3x2 + 4y2 axyFind the values of a which ensure that S is slopingupward when we move in the positive x-directionfrom the point (1, 2).(b) With the values of a from part (a), if you move inthe positive y-direction from the point (1, 2), doesthe surface slope up or down? Explain.
