hello,
i would like to plot a funtion in
two variables with a side condition.
first i defined the function like this:
f[x_,y_]=x*y*(3-x-y)/;
(y <= 3 - x);
then i tried to plot:
Plot3D[f[x,y],{x,0,3},{y,0,3}];
unfortunately, it does not give a graphic result (it says something like "not a machine number")
can anybody help? thank you!
