We have started to do Lagrange Multi. in my class and my book has a very short section on how to solve these. I was wondering if someone couls help.(adsbygoogle = window.adsbygoogle || []).push({});

The problem is f(x,y)=x^2-y^2 with the constraint x^2+y^2=1.

I have found the partial derv. but I am not sure on what else to do. Any help would be sweet, later.
