Texas Instruments TI-Nspire CX II CAS Color Graphing Calculator with Student Software (PC/Mac)

The calculator has a great array of functions for different kinds of math, and good software capabilities. Main drawback is that the UI and controls are difficult to navigate, will require a lot of getting used to

Its intuitive to use and after 2 days of practice you can get around it. Keep the booklet handy for when you need to remember how to do some more exotic stuff. You can create and edit python scripts on it ,from the device ,and the python library has all you need. Doesnt have 3rd party python libs ,but you can add them or copy the files. This python capability comes in handy if you need to roll your own stuff to help you. Build quality is good and it doesnt feel like cheap plastic.The battery seems to be accessed by unscrewing the back lid so this should make battery replacement easy. Quite nice mini computer to have around to help you.

This is the ultimate calculator. I used to have a TI 84 Plus CE but once I hit Calc 3 it no longer was able to keep up with the level of math concepts I was being taught. This calculator has so many available functions and the ability to simply type on the keyboard makes it even better. Totally worth every penny.

I have owned this calculator for roughly one month, and it has been an extremely impressive product. First and foremost, this calculator has CAS capability. For those that do not know, CAS (Compute Algebra System) is an addition to graphing calculators that allows them to manipulate equations by variables as symbols rather than as numbers. This means saying goodbye to factoring, basic algebra, and quite a bit more. It can also integrate and derive indefinites, with weird answers coming up only here and there. For the calculator itself, it looks good, I have yet to drain the battery 30% even after one whole month of use. In addition, the mousepad feature combined with a dpad is pretty neat. While novel, it’s pretty useful. Then, turning to the document based side of this calculator. As with most of the NSpire line, you are able to create documents with various functions. For this one, it has compatibility with graphing, images, text, math, Python program, ti program, tables, and even more. All in all, this is a top of the line device, and truly a godsend for any and all engineering students in college. My one and only caveat, which doesn’t particularly apply to me, but rather to those converting from a Casio, I’d that this calculator isn’t very easy to learn to use to its true potential.

IF YOU ARE A HIGH SCHOOL/COLLEGE STEM STUDENT, BUY THIS PRODUCT IMMEDIATELY. It pulls through. Not only does it do algebra flawlessly, but it can also do very complicated tasks like taking integrals, generating derivatives, and even solving systems of equations. The one thing to note is the learning curve. It is pretty significant. However, use it alongside all your work, and after a semester or so, youll be a pro. You can even load notes and such into its memory. I love it!

Got this for my son who needed it for high school and college calculus classes. Many schools provide these as loaners for students as well.

The best part of this buy is the desktop software. It makes it easy to write programs and do graph. Easy to learn. At first one needs to get use to the keypad. The rest comes with practice.

My high school sophomore is blown away by how awesome this is. Good…because of how much it cost.

Awesome calculator. It really helps my daughter with her school work

I despise this calculator. As a point of reference, my favorite graphing calc is the TI-89: the terminal-like interface woven into a sorta-windowed OS was perfect. The N-spire is the antithesis of TI-89: I have to make a new document to do anything beyond scratchpad calculations, which only seems justifiable as a method to prevent the calculator from becoming a gaming or cheating device by removing ALL flexibility and ignoring adult users who dont take standardized tests and can game if and when they please. This forces professionals like myself into this pedantic and arcane document system, so we cant just eg. write a quick function and use it flexibly if and when needed. Instead, everything is a laborious set of steps to follow; Even writing functions on the scratchpad is tedious because it only offers half the screen for editing!! Further, I think tokenizing everything is ridiculous and unnecessary; Where variables and functions end up being saved is completely opaque; The touchpad moves the cursor when pressing or tapping to select; And while Im not adverse to thoughtful and functional changes, I dont see why the placement of nearly EVERYthing had to be revised from the TI-8x series: Im CONSTANTLY trying to remember the six or seven steps required to do something that was only one or two steps max two decades ago. But the final nail in the coffin: dedicated ALPHABETICAL keyboard in a region (North America) where EVERY device with a keyboard has Qwerty (and most have touchscreens)! This really feels like a device created by educational elitists that dont realize (or have forgotten) that calculator games were a gateway to a lifetime of programming for an entire generation who now make the devices and apps enjoyed by billions.
