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

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

Para la Universidad esta perfecta, solo hay que meterle mente.

This calculator is great for graphing and other appliances, but it is not that easy to learn to use all its functions. I still have not learned all of them. The packaging was good, however the calculator did not come with a charging box, just the cable. Overall great calculator and do recommend buying if you are taking high level courses in math.

This thing is incredibly cheaply constructed and plasticy! The interface is ridiculously non-intuitive and the buttons barely work. Trying to use the touch screen is nothing if not nearly impossible. I had a TI-86 that worked great for over 20 years, and this thing is truly garbage by comparison. I would also like to review the reviewers of this product because I see this again and again. I couldnt understand how anyone could give this pos more than one star, so I looked at the four star reviews...The vast majority of people have really negative stuff to say about this pos, but they still gave it four stars!!!? People: you really need to grow up and give star ratings that reflect what you say not rate something high because psychologically you dont want to admit you got ripped off!

Upgraded to this calculator from a TI-89 Titanium. The interface takes some getting used to, but after you get accustomed to it, it is extremely versatile and much more powerful than the TI-89. While its not as powerful as a computer-based graphing calculator (obviously a computer is going to be more powerful than the tiny, relatively cheap calculator), its the best dedicated calculator Ive ever gotten my nerdy little hands on. The only downsides is that it isnt allowed on the ACT, but neither is the TI-89 Titanium, so if its between those two, pick this one! If your only use for the calculator is going to be high school classes and standardized tests, a TI-84 model may be right for you, since its unquestionably allowed.

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.

I’m a senior citizen who received a large portion of my education before calculators were invented. It was all slide rules and tables of logarithms. This device is utterly amazing. Texas Instruments in Australia have produced many useful YouTube videos that collectively demonstrate everything the calculator does. It will take a lot of practice to become proficient but that’s the fun part.

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.

With the price point of new TI Graphing calculators being so close, from the standpoint of cost alone it makes sense to get one of these rather than a new TI-83 Plus, TI-84 Color, or TI-89 Titanium, since this calculator can do so much more than any of those other models. The user interface (in terms of buttons and what is on-screen) of the nspire series of calculators strays fairly drastically from the traditional TI graphing calculators, so if you are buying this calculator for school, you should plan to spend some time out of class getting used to how to do things on it. You dont want to be struggling through calculations when in a time crunch of a test, for example. I recommended this calculator for all serious math and engineering students. Im so glad I bought one.

This is going to sound cliché but it’s true. This calculator or so powerful I have no idea how to use it. This is the best calculator on the market in my opinion (I’m an engineering student currently). It comes with a subscription for a year of free calculator software where you can do unreal things. You can upload just about any problem you could ever imagine. However, this dramatically impacts the simplicity. Doing even the most basic things on this calculator Before the tutorial or learning it on your own it’s rather difficult. It is easy to learn after some YouTube videos and practice but right out of the box you will have 0 idea how to use it. I always skip tutorials just like everyone but you’ll actually need to watch it for this calculator because it is literally to powerful. I found YouTube gave me a better understanding than their tutorial but either one works. After you have learned this calculator it’s potential is unimaginable.
