Every time a problem comes up that involves these two functions
\(max(x,y)\) or \( min(x,y)\)
I have no idea what to do (I only started seeing that recently). I am not talking about finding local minima or maxima (or saddle points) of a function using calculus. I usually see that in plain-old arithmetic problems actually.
Also, AM-GM (Arithmetic Mean - Geometric Mean) is still a bit new to me.
Could anybody link me to some problems (that aren't too difficult) on these two topics?
