Graphing Calculator Requirement

We strongly recommend, and calculus instructors usually require, a graphing calculator with "CAS" (computer algebra system) capability to do symbolic algebra and calculus. The TI-89 or TI-89 Titanium is the calculator that instructors and tutors are prepared to explain. Students with other calculators are expected to find a way to perform hand-held computations equivalent to the TI-89. Lower numbered TI calculators do not have the CAS capability and will fall short. The TI-Nspire CAS calculator (touchpad or clickpad) does have equivalent capability, but only with the added designation of CAS. (The TI Voyage 200 is also CAS capable but with a larger screen and Qwerty keyboard.)
