Homework Statement
find the max and min of f(x,y)=x^2y, constraint x^2+y^2=1
Homework Equations
None.
The Attempt at a Solution
I found that possible points use the procedure of the method of lagrange multiplier, I got [tex](\pm\sqrt{2/3}, \pm\sqrt{1/3}[/tex] so 4 points total.
But do I have to check the end point on the constraint? like points (-1, 0), (1, 0), (0, 1), (0, -1)?and y this latex thing won't work? help please. lol
