Geometer's Sketchpad: How do I put a grid over an image?

  1. May 28, 2008 #1
    Is it possible to use an image as a background to a function graph in Geometer's Sketchpad, so that I could superimpose a grid over a map? Does anybody have an alternative suggestion if that's not possible in GSP?

    Yes, it is pretty straightforward - see my post at mathfest.blogspot.com/2008/01/strauss-sketchpad-photos-quadratics-and.html

    Thanks for the link, great demo.

    For some reason cutting and pasting wasn't working for me on the machines at school - do you know if that is a recently added feature? Because the machines at school run GSP 4.06 and I have 4.07 at home (which did the job fine.)

    Hmm. I'll have to try harder on it at school now that I know I SHOULD be able to get it to work.

    I would guess that it was in 4.03, at least.
