I know this isn't exactly a homework question, and it may be in the wrong section, but I've looked all over the forums and could not find a better place for it, so I apologize if this is in the wrong section. I'm looking into buying a new calculator for my AP Physics class this fall and found what seem to be two promising products. The first is the TI-89 Titanium, which seems to be a powerful graphing calculator with pre-installed applications for AP Physics, and I thought it looked great. However, I then found the TI-Nspire, which seems to be newer and have more functionality. Apparently the Nspire has more memory, and all sorts of things that make it seem more like a computer. I thought the Nspire looked great and all, but the Texas Instruments website does not list the applications for it, and so I do not know if it has the power I want for advanced physics and such. So my basic question is, what which calculator would Physics Forums suggest for use in an advanced physics course (and future college science and math courses)? Thank you for your help and again I apologize if this is in the wrong section or has already been posted.
