2) Calculus concepts can be learned by viewing visual calculator animations.
3) Teachers and students can solve any Calculus problems immediately. Even complicated problems (i.e. 2nd derivative or vertical tangent lines of implicitly defined curves or solutions to differential equations and slope fields, etc...) can be verified immediately. Literally, any problem can be solved with the Calculus Made Easy program - an enormous help !!!

What Operating System does my TI-89 have to have?
You need 3.10 (Ti89 Titanium and Voyage 200 ) or 2.09 (TI89)   (To find your OS select TOOLS on the HOME SCREEN, select option A: ABOUT. You may have to update your OS using the TI Connect software to be downloaded at http://education.ti.com/us/product/tech/89/software/software.html .)   .

It is a wise idea to have the latest OS installed.
 

How about compatibility with Mac OS X?
TI states that TI-89 is currently not compatible with Mac OS X 10.6.8 . We suggest to either use a different computer (school, friend, neighbor, ..) or to use the free TI Linking Program TILP
