# Math Help - Multivariable Calc

1. ## Multivariable Calc

In my multivariable calc class we were given some problems to try to work. See attached picture for the problem. We were told to consider 3 cases. α < β, α > β, and α = β. I managed to get the first two but I need help with α = β.

2. you may use the result:
$\max\{x,y\}=\frac{|x+y|}{2}+\frac{|x-y|}{2}$
