[quote=Anonymous][quote=Anonymous][quote=Anonymous]TI-Nspire CX II CAS.

It’s the TI flagship, far more capable than TI 84, which will probably work just fine, but why not get an extra advantage if it’s allowed.

There’s a learning curve to Tinspire, but there are many resources out there, and it will save a lot of time. Virtually any calculator question on AP can be done with one input if set up correctly with zero chance of making careless mistakes. Only caveat is that it’s not allowed on ACT, but the model without CAS (computer algebra system) is. CAS solves symbol equations, nice to have in some instances.

HP Prime for an alternative with a nicer input interface and screen, but fewer learning resources.[/quote]

+1 for the Tinspire 2 cas. It’s a godsend. You can do everything with a few clicks, store variables, take derivatives and integrate, while the peasants in the class toil away buttoning on their ti84s.

With CAS, you forgot an integral, no problem, it will give you the answer, tricky limits, there’s a function for it, need to solve an equation use solve for symbolic, nsolve for numerical.

Only downside is you can’t follow the teacher for input, but it’s not that big of a deal to figure it out.[/quote]
All that effort fumbling with midget calculators, only to look over and see the student next to them using Desmos—just pointing, clicking, and effortlessly exploring vibrant graphs on a laptop screen[/quote]
