Hello, I am looking into getting a TI-Nspire CAS model and while searching around found the touchpad model.
I was wondering if anybody has experience with the touchpad on the Nspire CAS. Why is it somewhat cheaper than the regular TI-Nspire CAS? Does it have any fewer functions? Which one would you recommend, the CAS with or without the touchpad?
Would another calculator be better for AP Calculus and math in college?
