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

Love it and love the software it comes with

I bought this for my son for his 1st year of college. He is now in his second year as an engineering student and it is still going strong.

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

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

The only thing that I do not care for is the Graphics interface for displaying Calculus derivatives. I can not find anything very tutorial that will allow me to enter a family of equations required for (for example) the spring-mass system or pendulum equations with damping and resistance. I am probably just not doing it right but I can not figure out what I am doing wrong and I have bought and read all 3 books relating to the TI-Nspire. none deal with second-order families of derivatives.

I bought this calculator as one I can grow into as I take different college-level math and science courses. I LOVE how much it offers compared to other TI CX calculators, however, there is a flaw in the design that has become quite irksome over the past few weeks of use. The short buttons require more force to press than a typical calculator (you could take this as a good thing, as it prevents unwanted numbers/functions from being hit) but I have glossed over the keys enough times and it skips picking up a number I press. I calculate an answer, and find it incorrect because a number is missing. Then I have to scroll back and add the number in, taking more time than I want to spend punching at a calculator. I wish the keys were more loose like standard calculators and scientific calculators.

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 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.

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.

A handy tool for college maths and stats.
