(c) D < 0, (x,y,f(x,y)) is a saddle point (d) D = 0, test is inconclusive 3. Determine if any boundary point gives min or max. Typically, we have to parametrize boundary and then reduce to a Calc 1 type of min/max problem to solve. The following only apply only if a boundary is given 1. check the corner points 2.

Calc III (Spring ’13) Practice Final Page 9 of 12 8.(10 points) Find all the critical points of the function f(x;y) = x3+y3 3xy. Determine if they are local maxima, local minima or saddle points. Solution: We know that (x;y) is a critical point precisely when rf(x;y) = 0. Therefore, @f @x = 3x 2 3y= 0 =)y= x @f @y = 3y2 3x= 0 =)x= y2:
