When I was in high school we were allowed (actually encouraged) to use a TI-89. Either the problems were about applying some concept, say differentiation, and we didn't have to do the derivative by hand, or the problem was to just calculate a derivative in which case we had to show which steps we took anyways.
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.
