TI-Nspire CAS Graphing Calculator - NSCAS/PWB/1L1

Feature packed and excellent for the price

I have used this calculator extensively in my university level calculus course and the various features it has make the course much easier. You can solve integrals and systems of equations directly on the calculator. There is some sticker residue and scuffs, but for the price, you can't complain. A bit of rubbing alcohol gets the stickers off.Read full review

Satisfactory.

This thing is amazing--it will solve problems right from the math book. It has capabilities I will probably never use. Being used to the old HP-48 I am finding it difficult to do operations that were easy on the old HP. This is a matter of getting used to it. The HP had a great book that explained everything. Documentation on this thing is poor to very poor. Like all of these devices there are features that are inexplicably perverse. It seems you can store a function under a name, but you can't retrieve or edit it. I've looked high and low and tried everything I can think of. A variable, yes, Function, no. There are ways around this though. If you want something that will do algebra problems for you, this is it.Read full review

Good calculator, but if you don't get the owners manual with it you will not be able to use it and figure out all it's capabilities.

You need better manual. One supplied by the producer is useless for more complicated functions
