Global Extrema  LaGrange's Theorem
The following 2 questions are concerned with the optimization
of functions of 2 variables 1. Find and classify all local extrema
of f(x,y) = x^{2} + 2y^{2} x^{2}y 2. Let
f(x,y = xy  x  y +3 on the triangular region with vertices (0,0),(2,0), and (0,4) Find the global extrema.
