Anyone have any skills with Mathematica? If not, show how you'd solve it normally, maybe that will help me understand this problem better. We are going to start by computing the tangent plane to the ellipsoid x^2 + 2y^2 + 3z^2 = 1 at the point (x0, y0, z0) = (1/2, 1/6, 5/(6*(Sqrt [3]))) Define the Mathematica function f(x, y, z) = x^2 + 2y^2 + 3z^2, the values x0, y0, z0, as above (stored in variables x0, y0, z0),...

I. Chapter 3: Question 3.17 on page 104 from Besanko and Braeutigam 5th ed. Answer all parts of Problem 3.15 for the utility function U(x, y) = xy + x. The marginal utilities are MUx = y + 1 and MUy = x. a) Is the assumption that more is better satisfied for both goods? b) What is MRSx, y? Is MRSx, y diminishing, constant, or increasing as the consumer substitutes x for y along an indifference curve? How do...
