Per our last meeting, I researched how to grab a string like "x^2*sin(x)" and parse it into computer syntax so that we can make calculator like applets. I made an example involving a graphing utility and I will hopefully have some stuff made up for our next Flash meeting.

You have to put parenthesis around trig parameters and you have to use * for all multiplication. Just press Graph Me when you want the graph

This is really nice. Have you have any luck with the action script 2 version? I haven't had any luck with it yet.

I can't open the fla file. It tells me that it is an unexpected file format. Can you try saving it in a lower version?
