Graphing Calculator Help

[Alex]

For the most part the only thing me and my friends used our graphing calculators for was programing games into them. It was a good exercise. And then when we made it to the state math team competition* we wrote a virus into one of our games (it was a version of Defender) and spread it around the competition when we used the IR port to share the program with other people.

Much fun.

(where we were again not allowed to actually use the calculators during the competition.)

As I recall, though, the actual need to graph things generally wasn't very big once past the initial trig and calculus instruction and once you were into three dimensional equations the calulators weren't useful at all (though maybe they are now).
