I am trying to figure out how to find the min/max of a
threee-dimensional function with Maxima.
For instance, I am playing with the function f(x,y)=x^3+3*x*y-6*x*y
On paper I can easily find f'x f''xx f'y f''yy f''xy and find the
critical points, then check each one. Is there a simpler way to do
this in Maxima? I have googled but not found anything of this sort
(though there is a lot of good info about Maxima floating around the
'net).
Just to prove that I'm not asking someone to do my homework (and yes,
this _is_ a homework question), the solution set is {(0,0,), (0,2),
(1,1), (-1,1)}.
