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

Just what she needed

This is obviously a very capable calculator which is why this gets 4 stars, but there are 2 things that I cant believe passed quality control. First one, when the calculator sits with its back in its sheath on the table and you type it will rock back and forth. I have a cheap Ti-36 that does not do this. My friend also bought this calculator and has the same issue. Second is it only lets you type super slow otherwise it stops recognizing the input, once again my dirt cheap Ti-36 does not have this problem and can accept a far higher input speed. For the money and given that this isnt the first iteration Id expect fundamental things like this not to be an issue. Also really not a fan of the baby blue as the only color option. Mathematically, no complaints, but thats to be expected, this is the top tier calculator. Also needs a higher res screen, its 2019.

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.

I like nearly everything about this calculator, except for the fact that it uses the old school USB charging port of Type B mini. Why in the world did they not finally upgrade to USB Micro or better yet, USB C?! I understand that they standardized with their other products, but at some point, they have to ditch the old. Aside from the charging port, I really like this calculator and highly recommend it. There is a bit of a learning curve to using it as it is quite a bit different from the standard TI-84 and such, but it is way more powerful. The touchpad is also a bit tricky, but usually, it cooperates with me.

I used this for both of my college algebra classes! The only bad thing I have to say about this is that I wished I would have had this in high school! It would have saved countless hours of math homework time! But I am glad that I know how to do the problems without a calculator, but it does help save A LOT of time. If you are getting wrong answers, it is because you are not entering in the stuff correctly. My teacher showed the class how to enter in the problems so I had no trouble with it. You can google how to use it if you are confused.

First, it arrived quickly and in very good condition. Besides the manufacturers package (with the manuals and an USB cable) it was also sent in a bigger box with plastic airbags, so it was very good protected. Regarding the calculators performance, so far very good. I used to have the first nspire CAS, and this one is faster from the beggining, it boots faster than the old one. I got this one as replacement for the old one (I had an accident with a cup of coffee) and I will test it further in the next days but so far very happy.

This thing is awesome! It is a bargain to boot. Totally cool! I do wish the keyboard was a QWERTY keyboard instead of the A-Z keyboard that it has. So one thing needs improvement. The rest is great. I love being able to tinker in Python on it.

It is a great calculator and was a good improvement over my ti-84 that I had for a few years. If you have previously used calculators with graphing functionality and are they type of person who likes to pick through the settings It is very easy to get used to. Depending on if I remember to turn it off when I am done I can get it to last around 2 weeks on a single charge and despite the long lasting battery processing speed on this calculator is much better then ones I have previously used. I am currently an engineering student and having a good calculator can make a huge difference in ones studies.

The computer algebra system that comes on this particular calculator is a game changer. I’m a mechanical engineering student at Texas A&M university, and this calculator saved my a** last semester in thermo, mechanics of materials, and the electrical engineering class. Being able to solve a system of 3 equations with 3 unknowns in variable form is AMAZING! I know that there are websites to do this, but the cool thing is that you can use a calculator on pretty much any test, so you are golden! Stop wasting time doing math by hand, learn the functions of this calculator and save your head from being repeatedly thrusted into a wall when you make a stupid algebraic mistake!

Awesome calculator will do just about anything you throw at it. Interface is ok, on par with other TIs. Its just a matter of finding out how to do something. The main menu is a little awkward. Need a touch screen as the curser is archaic. Need 2nd entry shortcut. Great once you get used to it, but why not make it more intuitive. Dont know of a better calculator...
