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

Great calculator for advanced math. Clear screen, fast response, and perfect for AP and SAT prep. My son loves it!

This is a great calculator for engineering students and professionals. You can program on it and handle complex calculations, graphs, and more — it’s a very powerful tool. It also arrived quickly and well-packaged.Solid choice if you need a high-performance calculator for advanced work.

I was trying to find a graphing calculator for an online calculus class that I was taking. The class went all the way from precalculus to Triple integrals, gradients, curl, divergence, Green's theorem, and so on. In doing the research online, it seemed that many if not most recommended checking out this Ti calculator. I got it and used it for the class. I was amazed at how easy it was to put in the nested integrals. It handles coordinate changes easily and has really good graphing capability. The bonus has been the online software that comes from Texas Instrument education website. It has a nice emulator or screen capture function. Really good help system and guidebook for functions. Excellent instrument and good replacement for my Ti Voyage 200 that crashed after 20 years.

Hello everyone!I am learning Precalculus in order to better understand Calculus. Both are usually neededTo solve Calculus problems. This Ti- Inspire Calculator is geared toward solving many mathematIcal problems and will tackle very nicely the realm of Calculus - The display, overall appearance and the graphics will add to the exciting world of mathematical inquitry.From Brian. Thank you for reading. GOD BLESS YOUR STUDIES.

I'm a college student, studying for a degree in Economics. Needless to say, my life these days is all about maths. For the past couple of years I'd been using the TI 84 Plus CE which, although it's a pretty good graphing calculator all in all, has it's issues, but I is the recommended calculator for all the classes I've taken so far. So, imagine my surprise when I found out about the Nspire calculator series.The TI Nspire CXii CAS is an extraordinary tool. It can factor polynomials, calculate complex equations giving the answer in terms of i, and graph in 3D. That's right...Z-axis! The CAS in the calculator's name stands for Computer Algebra System. It allows you to solve polynomial equations in any number of variables and give answers in terms of those variables. That's right! You don't need numbers!One of my favorite upgrades is in the graphing feature. In the TI 83/84 series, if you wanted to trace a graph to a point of interest that was not in you current viewing window, you needed to leave the graph and go to a separate page where you needed to reset the viewing window to include your point of interest, then you had to navigate back to the graph and calculator would redraw it often very slowly. The Nspire CXii, on the other hand, allows you to make adjustments to the screen from a pop-up menu that comes up while you're still in graphing mode. And, if you don't want to bother with that, you can use the track pad to pick up the screen and move it, or you can just trace your chosen graph in either direction and when you reach the edge of the screen, it moves the screen to match your movements. You can also split the screen to view your table of values while looking at your graph!I'm still discovering all the things I can do with this calculator and I'm sure I'll continue to discover much more as I advance to higher levels of maths. There are entire apps dedicated to geometry, statistics, trigonometry, and more. Also, apparently there is a whole set of science tools witch can plug into the calculator to give you data on a wide range of things; heat, speed, velocity, etc. So much good stuff.Ok, now for areas that could use improvement. First, there is set of educational software that you can download and access for free when you purchase the calculator. Unfortunately, the software is only compatible with Windows or iOS. I, like many students, am a Chromebook user. Not making their systems compatible with Chrome OS is, in my opinion, an epic fail. I contacted their customer service department and suggested that improvement as well as a cloud computing option for those who want to access the tools from any computer. I was told that they passed my ideas on to their product development department.All in all, though, this is a great calculator! I'm sure I'll get several years of enjoyment out of it as I work toward my degree. It's way more intuitive and easier to navigate than the TI 84. That said, if you're like me, you'll need some help to get started. There's a pair of books by Lucas Allen in the Kindle store that really jump-started my understanding and enjoyment of the TI Nspire CXii CAS. I highly recommend reading them.

Saw many reviews about the battery not working straight out the box and got concerned. Took it out the box and plugged it into my laptop to charge, after 20 mins stays on 0% and dies after being unplugged. I then take out the plastic battery tag in the back and then plug it into an outlet. After 30 mins it still stay 0% and dies when unplugged. I left it charging for an hour and it still says 0%, but this time when I take it off the charger it stays on. After a few minutes when I looked at it it then said 75%. I've had it for a few days now and its working perfectly fine. Also when I contacted support to get a new battery (before I realized it was fine) they gave me a phone number to call and when I called it the person was so confused and said that Amazon should NOT be giving out their number to help. I hope everyone calculator works even after the heart attack it gave me in the beginning.

The calculator itself is fantastic. I love all it's functions. It's easy enough to work with as well. The trackpad is pretty useful and even fun.Playing/programming games on my calculator is of course a classic thing to do. I didn't get to experience that as a kid, so as an adult I'm just happy to get to do so.The only complaint I really have is the learning curve of the UI for the PC program. It's surprisingly difficult. Maybe it's just because I'm neurodivergent, or because it's meant to be taught about in a cvlassroom, but without an instructor to tell me what I'm doing, the difficulties with the UI alone have set me back in learning the unique Lua language the calculator uses for programming.It looks like I won't be programming 'The Gates of Zendocon Lite' anytime soon.With all that being said, I am in love with this calculator, and look forward to having it as my companion throughout years and years of physics classes and programs.Don't mean to be emotional, but it is beautiful.

Awesome calculator required for higher math. Electrical Engineering Students must have!
