> I never even thought about that. That website says it has all the common intro to physics equations written down and can save me an assload of time if I download it into my Ti-89. Only problem is I have heard alot of calculator downloads are infected or can crash your calculator. Does the calculator have some kind of backup or defense against crashing or infection?
