I got the same answer plugging and chugging by copying and pasting your email into Mathematica (v5.1): In[1]:= Integrate[Max[x,y],{x,0,1},{y,0,1}] NIntegrate[Max[x,y],{x,0,1},{y,0,1}] Out[1]= !(2/3) Out[2]= 0.666667 Chris Duncan Quoting Bidule <toto at truc.com>: > Hi, > > I've computed the following two expressions: > > Integrate[Max[x, y], {x, 0, 1}, {y, 0, 1}] > NIntegrate[Max[x, y], {x, 0, 1}, {y, 0, 1}] > > which result in very different numbers.
