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

This calculator is jam packed full of features and functions. Definitely worth the hefty price tag for anyone majoring in engineering, physics, math, etc. Not as intuitive as using a TI83 or TI84, but far more powerful. The rechargeable battery also lasts a really long time, with a very long standby period.

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.

Es excepcional resolviendo operaciones que pueden llegar a ser muy complicadas. La uso para mi pregrado en ingeniería química pero es útil en muchas otras ingenierías. Tiene gran variedad de funciones, es potente y realiza cálculos y gráficas rápidamente. Al ser una herramienta compacta y completa, me ayuda mucho. Vale la pena.

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.

This calculator is very capable of all sorts of math (specifically the CAS version). If you are a student and your class allows this calculator, it takes much of the leg work out of math.

This is a very powerful and professional calculator. I have been using the TI84 since middle school, and now that I am almost done with college (majoring in mechanical engineering), I thought it was time to upgrade to a more powerful calculator, and I can say that I am very impressed with this calculators abilities. I wish that I had this going through all of my math classes in college. Getting used to the keystrokes is very difficult and will likely take years for me to feel as comfortable as I do currently with my TI84, but it is worth it. I highly recommend this product for someone that is in advanced mathematics (Calc, Lin. Algebra, Differential Eq, Statistics, etc). I would not recommend this to someone in middle school (and maybe even high school) as this is a very advanced calculator and a lot of its features wouldnt even be used by a middle or high schooler. I hope this helps.

Muy útil para optimizar la resolución de procesos matemáticos, cuando tu objetivo no es evaluar tu habilidad matemática para resolver ejercicios, sino aplicar los resultados a un problema en específico como en el estudio de ingeniería. Diversidad de funciones, las cuales en muchos casos se pueden utilizar de manera intuitiva. Además de cálculos, permite trabajar con gráficas, las cuales en 2D tienen muchas opciones de análisis; por el contrario, las gráficas 3D si pueden quedarse limitadas cuando se desea trabajar en dicho espacio.

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).

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.

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.
