Hi, I use Mathematica 6 on a PC (Intel Celeron CPU 2.6 GHz, 256 RAM) under Ubuntu 7.04. When I run the command Plot3D[f,options] it doesn't display me the function graph if f has a complicated form. If f it's enough simple, the function is displayed. For example the command Plot3D[Sin[x+Sin[y]],{x,-10,10},{y,-10,10}] shows me the graph, but already for Plot3D[2 [Sin[x+Sin[y]]],{x,-10,10},{y,-10,10}] I can't see it, just the 3D box, where should be the graph. Does anyone know the reason? Thank You in advance!
