When you first use this calculator you will probably be a little confused with the whole document based UI. In conclusion, the programming feature will be most useful for creating and combining functions for calculus, but not for much else. You have to exit the calculation screen and then open the document with the program and run it from there. So if you are doing calculations on the calculator screen you can’t just quickly run a program and then go back to what you were doing. You must access it for the document you made it in. On top of all that, you can’t access the program from any screen or document.

That is, creating a program that takes in a hand full of numbers and then instantly outputs a result. So, in the end, this really only leaves you with one option. The programing language itself is also a slightly different version than it is on the TI-84/83 models. But there are way fewer command options and they left out some of the most important ones, like menus. Once you create a new program you can edit it similar to the way you edit on a TI-84/83 by selecting commands from menus. You start out by creating a new document and then inside that document starting a new program or function. You can however, program the TI-Nspire CX CAS…sort of.Ĭreating a program is more tedious than I think it has to be. This calculator and most other calculators do not have the programming capabilities that I love on the TI-84/83 models. The button not only gives you sin cos and tan and their inverses, but it also has csc sec and cot. These expressions are both equal it’s just unclear which is really “simplest form”. The only problem I found was that if the simplest form was, for example, csc, the calculator may output 1/sin. As shown below you can even simplify trig identities. Simplifying basically anything on The TI-nspire CX CAS is also a piece of cake since the calculator will give exact answers. All you have to do is, type in the action you would like the calculator to perform.

It’s also pretty easy to remember how to access these features. You can also do things like factoring and expanding polynomials. If you have a quadratic equation, like in the example below you will be given multiple answers. Once you do this the calculator will give you an exact answer. You can solve any equation from the calculate screen by typing “solve” and then in parentheses typing in the equation and then after a comma the variable you want to solve for. This is definitely one of the best features of the TI-nspire CX CAS.
I will talk more about these things in the next section of the review. Also, the nspire does not have the same programming capabilities that the TI-84/83 models do. The HP Prime is an alternative that is similar to a classic graphing calculator in terms of ease of use, and is arguably just as capable. The document-based UI makes the calculator less user-friendly and you can’t always access all the things you want from one calculation screen. This, to us, is the major downside to this calculator. Unlike the TI-84 models, and most other calculators, The TI-nspire calculators have a document-based user interface. If you want a calculator that can do much of your Algebra 2 content for you, this may be your best bet. There are apps for drafting shapes, making spreadsheets, analyzing and collecting data, and many more. As well as being an amazing graphing calculator, it has many other features that aren’t standard for most calculators. When you get an answer from this calculator, it will be in exact, simplified, form (unless you want a decimal). The Computer Algebra System (CAS) is an amazing feature that can handle many tasks that are tedious to do by hand. The TI-nspire CX CAS is Texas Instruments’ most advanced calculator yet, and probably the most advanced device that you can use on the SAT.
