    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.

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