Zusammenfassung: I got this for someone who's taking Calculus III (The one where they deal with many levels of integrals, and crazy coordinate systems); there was a bit of a learning curve for them, but they ended up really loving the product once they got used to it.
Exzerpt: This calculator works great for the higher level calculus that I am required to take. Battery life lasts and works while plugged in. For those looking for assistance with that type of work this is the calculator. If not save a few dollars and get the lower model.
Zusammenfassung: this was not the calculator my son had me searching for. He originally wanted the TI-89. When i started researching i fount that it was not usable in all formats and was banned from standardized tests. the Nspire CX is not. and HE LOVES IT. And it was cheaper than the TI89
Zusammenfassung: I give 5 stars because it has gotten me through calculus so well. If it can can work perfectly to even the hardest further math then any other under that level can be done with ease. It has taken a while to get used to from my old TI-84 calculator but I assure that it is well work it.
