Which calculator do you use / help?

<p>So basically my sister is done with all her math classes from college and I've inherited a small collection of graphing calculators.</p>

<p>TI-83 Plus
TI-84 Plus Silver Edition (currently using)
TI-89 Titanium
I also have access to a TI-Nspire CAS with Clickpad, my calculus teacher gave these out to each student to use on the AP test. </p>

<p>I was just wondering which graphing calculator most people use in higher math classes and if I should switch to the TI-89 or Nspire or stay with the 84, which I'm really familiar with. I'm in Calculus BC right now and I want to be able to use the calculator on the AP exams and SAT.</p>

<p>My parents are also willing to buy more calculators lol so should I invest in my own TI-Nspire? If so, which model? I would hate to use my teacher’s for a year and then be without one in MVC.</p>

<p>Any form of ti 83/84 (prefer the 84/SE version) will get you through Pre-Calc and most of Calc. Learning ti-89 will be useful only for AP Calc. Don’t switch to the TI-Nspire unless you have the time and patience to learn the format of the device and master its capabilities.</p>

<p>TI-84 Silver Edition should be just fine.</p>
