Texas N3/TBL/1E1 TI-Nspire CX Graphing Calculator, Black

I bought the TI Nspire CX for my A-level maths qualification, as I knew I'd get plenty of use out of it. It has many features which make it incredibly useful for my course, such as numerical calculus (Allowed in exams, gives a value for differentials and integrals, allowing me to check if my value is correct), vector functionality, graphical plots (f(x) function and x,y relations). The calculator logs calculations in a way which is easy to go back through, to check your calculations and such. It definitely takes some getting used to though, so I wouldn't recommend getting it a week before your exam. The alphabetic keyboard does not feel natural like a qwerty keyboard, but you mainly use the keyboard to store variables (it's useful to be able to store something like me as the rest mass of an electron, and all variables can easily be found by pressing the VAR button). This calculator has many functionalities, and the only downside to that is there is not a ton of information out there on how to use each one to a high level, but I've found just playing with it allows you to find out a lot of the things it can do.The calculator has a press to test feature, this locks the stored data and can lock certain functionalities as well. This is useful for exams as it means I can keep any notes I've stored on it without having to wipe it every time, but you can only leave press to test mode by moving a file you need to create into the calculator using its PC link software, not the easiest thing to do but it does work.Although the calculator cannot give you indefinite differentials and integrals, it can plot a differential of a function, so you can easily plot the differential of an integral to see if it matches the original function. The calculator will not give you exact values, such as (root3)2, instead it will give you a number.This calculator is very useful for me, and I use it for many things, as it is very simple to use. I'm very happy I bought it, even though it is very expensive for a calculator because I do find so much utility in it. If you have any questions regarding the calculator, I would be more than happy to answer them.

Hi, I recently purchased this to aid me in my A-Level cores 3 & 4 maths exams. A friend in the class has one like this, and he was getting the best grades, so i figured this may help me. Just a word to the wise to, this is THE BEST calculate by TI that you are allowed to take into exams, pending you are allowed graphics calculators, as any more expensive ones are illegal in them [for me anyway] due to, from what i understand, having a qwerty keyboard on it is illegal, whereas this doesn't. It didn't give me answers, but it was really good for checking final answers with the likes of modulus and definite integration. It was a shame my exam board really screwed up with both papers this year, both being insanely difficult in comparison to past ones, but i feel i got more marks by being able to check my answers at the end and correct if they went wrong. THIS WON'T DO QUESTIONS FOR YOU, as most of the time it now asks for exact answers (i.e. surd or Ln form) due to the rise of the graphical calculator, so you will still need your witts about you.Providing you are used to technology, i would say get it at least 1 month before exams to be fully aware on how to use it to its full potential. I would highly recommend this for people who are say C/D A-level grade maths students as I feel it may have the potential to knock up your grade by one or two.

I have been a fan of Texas Instruments calculators since I got the TI-57, then TI-58 and finally the ~TI-59 during the 1970s. The TI-59 in my mind is the best calculator ever.So, I was perfectly happy to buy a new Texas Instruments product. Right now it is charging and I am sure that using it will as much a pleasure as was using their earlier calculators.I have already bought the "TI-Nspire for Dummies" book, expecting that it would supplement what came with the calculator. What a disappointment I got. There are two license documents, one warrenty leaflet and an instruction leaflet which makes the word "superficial" gain a new meaning. I would have expected that even if proper printed manuals weren't supplied (those which I have for earlier TI calculators are always excellent), I would have expected a CD with the detailed manuals. Instead I will need to do some Google searching. One star knocked off for the lack of real documentation. Why is it that as technology becomes more complicated, manufacturer's think it is acceptable to provide less documentation with the products?

In the past I have taught students to use Casio and earlier TI graphics calculators, so I'm ideally placed to make this comparison.Without the slightest doubt, the TI-Nspire CX is by far the best, and I unreservedly recommend it. It will most certainly help students in their exams.It's only a pity that, out of ignorance or maliciousness, so many UK schools lie to their students and tell them that they are not allowed to use this calculator. They are, and they should!I'm adding an addendum to this review on 20/05/2017, for prospective maths A-level students. I've recently read that for the new linear A-level (i.e. for all students starting A-level maths in September) statistical tables will no longer be supplied. While other cheaper calculators can, to some degree, fill this gap it makes a lot of sense to get this one. It does the job really well. With the latest OS update you can even do things like an inverse Binomial Distribution look-up, which your cheap calculator won't do. As is usually the case in life, you get what you pay for. Does it really make sense to jeopardise that A* grade just to save a few quid?
