I build this tutorial for a TI-89 for a friend on parametric equations and trig from an old prank I pulled on my Calc 1 instructor. It shows how to doodle with math on the calculator by learning how parametrics work. It's also a funny prank to leave on a classmates y= editor if you're bored. Anyone have math hacks, tricks, pranks, or other stuff to share? Questions are welcome too. ;^)
