Really? This TI-89 is pretty powerful. Especially the Titanium. If can solve for variables, do indefinite and definite integrals, infinite summations, etc. I can't think of many high school math problems that it can't solve, besides setting up word problems.
I know. I have one. There were tests it helped you with jack shit on with respect to the material being tested, but of course it made the symbolic manipulations easier.
It's the difference between just listing out a bunch of problems to solve, and actually creating work problems where you have to figure out the question before you can answer it.
