    If he has MS Windows, I like this program WinPlot:

    it can graph functions, 3-dim surfaces, implicit functions, differential equations, and more :)
    It’s not as powerful as some other programs out there (that you have to pay for), but can make better graphs then a graphing calculator (in color too, and then you can print them/add them to a document). I used it to make the “proof without words” of the pythagorean theorem that’s my Y!A avatar.

    Best of all, it’s free! =)
