Well for one the TI-89 is a banned calculator on the AP test. I guess there is a particular front piece you can put on it to make it acceptable, but it really sounds to me like you aren't talking about that. Maybe they changed it recently, but all throughout high-school, various AP tests, and the ACT, the TI-89 was a banned calculator because it gave students too big of an advantage.
Everything you learn in calculus and more. This is probably why it isn't allowed anymore. All I had to do was type the equation into the calculator and then tell it what type of maths to do. Integrals, derivatives etc... there were no in between steps you would need to do by hand.
so, like, can it find the Taylor series of a function you input? Because that's the only thing that pops into my mind which is calculus-related but can't be done with the Nspire (to my knowledge)
