my teacher gave us a b!tch of a problem on our last test and since no one got it 100% right, he told us to try to figure it out for homework... the more i try, the uglier this problem looks... PLEASE tell me theres an easy way to do this problem that i'm not seeing...
Find the absolute max/min values of f(x,y)=e^(-x^2 - y^2)*(x^2 + 2y^2) on the disk D with x^2 + y^2 <= 4
any help is very much appreciated
