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

This calculator will help you cheat or check your work. Unlike older calculators you can put the problems in just as they appear in written form. Downside is you dont learn anything besides operating calculator.

Expensive but worth the investment. You can find it cheaper elsewhere but if you want the peace of mind that it will be perfectly new buy it on amazon. The added Computer-Algebra-System isn’t something most people need but it’s worth the extra money as it makes problem solving very easy. It comes with a code to download an emulator on your computer. I use that to right notes on my computer and download them straight to the calculator (very easy to do). It takes some time to get used to the way you use it. It’s more like using a computer but you will get used to it. If you plan on doing anything STEM related this is a great calculator to have. You can download software for almost any subject from algebra to A high level Differential Equations class. If you want to save a little money the previous color model is almost identical aside from color (at least in my experience).

With the price point of new TI Graphing calculators being so close, from the standpoint of cost alone it makes sense to get one of these rather than a new TI-83 Plus, TI-84 Color, or TI-89 Titanium, since this calculator can do so much more than any of those other models. The user interface (in terms of buttons and what is on-screen) of the nspire series of calculators strays fairly drastically from the traditional TI graphing calculators, so if you are buying this calculator for school, you should plan to spend some time out of class getting used to how to do things on it. You dont want to be struggling through calculations when in a time crunch of a test, for example. I recommended this calculator for all serious math and engineering students. Im so glad I bought one.

Excelente calculadora científica, pero de difícil uso, es más bien una computadora programable manual, aun no logro sacar provecho de la misma, y no es tan simple utilizarla (yo la necesito para mis estudios de ingeniería), trae muchas funcionalidades y en multi-idioma, pero no venía con un manual de uso... es compleja, pero se nota que una vez que se logra entender como utilizarla debería ser una fantástica herramienta de ingeniería.

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.

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.

My kids needed this for school, good price and arrived quickly

So listen to video to get tips n shortcuts. Slight learning curve when using for exams, just make sure it’s deg or rad n the right sig figs! Also, your 2 fingers can enlarge the graphs! Lol. Currently, using for AP chem n AP calc.

I am going back to school. From my previous college days, I was using a TI 82. This is much better. The screen is easier to see and it give answers in easy to use format instead of just giving a decimal answer. This has, however, caused me some issues on several math tests. If the majority of the problems you are working on will require a decimal answer, change the setting to approximate instead of exact. If you dont change that setting, you can still get a decimal answer by hitting [ctrl] [enter] instead of just [enter]. If you do hit [enter] then try to view the decimal answer by hitting [ctrl] [enter] be sure to check the screen to see what it calculated. Sometimes it repeats the last calculation on the formula you are using so instead of a numerator divided by a denominator it gives you the numerator divided by the denominator divided by the denominator. You just have to verify what it calculated. I am still trying to figure out the Documents feature but overall, I am extremely happy with this calculator. If there is a drawback with this unit, it is in the documentation. They could have provided more examples of how to use the features. I am using YouTube videos to cover what I still need to learn.

This is an incredibly powerful calculator, only really necessary for university level engineering or similar. I honestly wouldn’t recommend it for less than that because the menu based interface can slow you down and takes a while to learn. If you don’t need to do matrices of complex numbers in phasor form then get a TI84
