This app is simple and similar to our TI-84 triangle solver program. One of the most convenient apps on the Prime (and it may save you on your SAT) is the triangle solver. Basically, you can plug in different (separately sold) sensors into the Nspire and collect and store data all with your calculator. But The TI-nspire is also able to collect data through accessories from Vernier. (We'll talk more about this in the Usability section). One of the reasons for this is that the Nspire creates "documents" every time you use an app. Just from looking at the pictures, it would seem like the HP Prime has much more, but a lot of functions are packed into one app on the Nspire that might be spread throughout different apps on the prime.īoth calculators have apps for data analysis, but the Nspire is better for data storage and collection. Below is a picture of both of the app selection screens so you can get an idea of what kinds of things you will be getting. But we will talk about the differences between these two calculators and their apps. We won't look at every single app on each calculator because most of them are very similar. Some will be super useful and some you probably won't ever even open. The n-spire does a lot more things automatically but the prime has more typable commands that give it extra functionality.īoth of these calculators have a good number of apps to choose from. Well that depends on what you are looking for. We found it just slightly more intuitive. What we found is that this is really the only place where the n-spire is easier to use. The bottom line is that these are some of the best two CAS systems that you can get in a calculator. Note that this isn't nearly all of them as we couldn't fit them all on one screen. The menus below should give you somewhat of an idea of the kinds and amounts of functions that you will be getting with the CAS on each calculator. (TI-nspire CX CAS on the left, HP Prime on the right). Below are some examples of both calculators of what they can do with their Computer Algebra Systems. That means, simplified radicals, fractions, and trig functions, not decimals.īoth of these calculators will most likely be able to do way more than you need or expect from a calculator. The CAS will also give you all of your answers in simplest exact form. Most graphing calculators do not have a CAS, but you will probably find it to be the best thing about either one of these calculators.įor those who aren't familiar with what a CAS is, it basically gives your calculator the ability to solve, simplify and factor expressions that have variables. For most people, the most attractive thing about these two devices is their Computer Algebra System (CAS).
