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

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.

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.

Llegó antes de lo esperado, sellado y en buen estado. La calculadora venía full-bundle con la licencia para el software de pc y lo bueno es que se carga a través de USB y no usa pilas

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.

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.

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.

I am going back to school. From my previous college days, I was using a TI 82. This is much better. The screen is easier to see and it give answers in easy to use format instead of just giving a decimal answer. This has, however, caused me some issues on several math tests. If the majority of the problems you are working on will require a decimal answer, change the setting to approximate instead of exact. If you dont change that setting, you can still get a decimal answer by hitting [ctrl] [enter] instead of just [enter]. If you do hit [enter] then try to view the decimal answer by hitting [ctrl] [enter] be sure to check the screen to see what it calculated. Sometimes it repeats the last calculation on the formula you are using so instead of a numerator divided by a denominator it gives you the numerator divided by the denominator divided by the denominator. You just have to verify what it calculated. I am still trying to figure out the Documents feature but overall, I am extremely happy with this calculator. If there is a drawback with this unit, it is in the documentation. They could have provided more examples of how to use the features. I am using YouTube videos to cover what I still need to learn.

Es un excelente producto para aquellos estudiantes que pueden usarla como herramienta. La recomiendo para ingeniería y ciencias exactas.

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.

Perfect item, just expensive
