I don't know how to do it in excel, but this program will. It is really easy to use, and is free to download. I didn't write it, but I do use it alot. Graph It is open source if you like that sort of thing. I hope this helps.
Hi, thanks for the link. How do you write the expresion in? I am trying but it will not accept it.
