I think its a bug. The function Plot in Mathematica 6.0 trial version makes a graphic without ploblems. i buy the standart version 6.0(the same) and it gives me in the out: Graphics, but dont draw the graph and send me a message: Export::obsalt:Display is obsolete. Instead, use Export. >>
When i click the arrows i can see the export function and its definition but i dont understand the change between the trial and the standart edition.
Can someone answer my question and explain me another way to plot a fcn. Thanks.
