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

This thing is awesome. When calculating something like cos(pi/4), it automatically gives you sqrt2/2 instead of some long decimal. It also finds the derivative function rather than just the derivative at a point. Additionally, it will store an entire funtion, so you dont have to retype some long complicated funtion over and over, you can just hit (A), which the calculator knows is that function. These are things other calculators cant do. Some say that its hard to figure out, but its relatively easy to learn. I will note that a lot of this extra stuff is only with the CAS model of the nspire, so make sure you get that CAS version. Either way, this is a pretty awesome calculator. Plus, its approved for AP Calc tests!

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

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.

The learning curve is a bit steep if you are not familiar with TI calculators but the payoff is worth the effort. It does most everything you might want to do in mathematics. From algebra to xyz plots the TI-Nspire CX II CAS color graphing calculator will do the job. It is light weight and the keys are easily accessible to larger fingers. The screen is a good size too and easy to read. However, it would be helpful for older eyes if you could enlarge the mathematical text. You can enlarge the document text. I graduated from the TI-84 Plus, and I am not at all disappointed, in fact, very happy I did.

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.

En mi vida de estudiante de ingeniería tuve una Casio fx 750. Hoy después de 20 años como profesor universitario encuentro esta calculadora imprescindible para un conocimiento claro y eficiente en todas las áreas de la ingeniería civil. La estoy recomendando a mis estudiantes. El interfaz de usuario mediante PC es muy sencillo, la curva de aprendizaje ha sido buena y cada día descubro cosas nuevas. Tiene un gran potencial. La batería es recargable y rápida, lo hago con el cable al PC. Lenguajes de programación; TI- Basic, phython y Lua, solo la he trabajado con TI- Basic.

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.

The TI-Nspire CX II CAS is a fast and powerful calculator with a CAS that, like the TI-89 Titanium, is fully integrated into the Scratchpad and Calculator app. Aside from CAS-specific functions, the user interface and menu trees are nearly identical to the TI-Nspire CX II. See my review of that model for more information.

La tecnología que trae es sorprendente, los gráficos, connexion a la Puc es muy bueno

This is the best calculator I ever purchased. The battery life is top-notch as I have used it for weeks on end without worrying about charging (keep in mind I dont use it everyday/ all day). The ability to learn how it functions is relatively easy. Operational videos on 3rd party sites will definitely provide you with the necessary insight. Lastly, the interface is okay as it can be overwhelming for someone new to the TI Calculator series.
