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

Im an adult engineering professional, not a student. Really like the CAS system that solves, simplifies, factors, expands, etc. algebraic expressions. No need to convert systems of equations to matrices. No worrying about silly mistakes in algebra. I really like that expressions can be variables, makes substitution super easy. Im coming from a TI-82 (it still works!) so I felt fairly comfortable, but still had to watch a few YouTube videos to get the gist of documents and an overview of the features. Read the manuals, watch videos, google, etc and the fun and power slowly reveals itself. I installed the software, calculator comes with a license but you have to download from TIs site. Used the software to upgrade the firmware to latest version no problem, transfer files to and from calculator, and the software emulates the calculator so you can use your computer for editing, screen sharing, etc. All very cool. Build seems solid, though not as rugged feeling as my old TI-82 which is built like a tank and survived many drops and abuse. Bought a padded case for this one, which I dont think is needed for the older models.

My high school sophomore is blown away by how awesome this is. Good…because of how much it cost.

I am horrible at math. I mean HORRIBLE! I bought this at the tail end of my algebra class and it was okay for what use I got out of it. Now I’m in Chemistry and omg, it has helped me so much! It’s been trial and error in trying to figure out the functions of this calculator but for someone who’s never used something like this, it was easy enough. I’m excited to use it in my Statistics class next term.

Awesome calculator. It really helps my daughter with her school work

This calculator was an upgrade to my TI-84, as I needed the Nspire for the imaginary portion of my Intro to Circuits class. The calculator has a lot of functions and can solve almost anything for you, including Calculus, Statistics, and can even run some games if you install them. The main drawback are the buttons, which are much less user-friendly than the classic TI-84. The buttons do not give much physical feedback compared to the 84, are much more noisy, but most importantly, sometimes it seems that the numbers do not always register, so you always have to max sure you are inputting what you are clicking.

Review for the Texas Instruments TI-Nspire CX II CAS Pros: Its a calculator that does algebraic equations. Great battery life. Cons: Everything else. Imagine having to spend double the price for something you already have thats worse in almost every single way. If this wasnt required for school Id just use an app (mathways, desmos, etc) or literally anything else. The mouse pad function is literally the worst Ive ever encountered. The shape, response and feel and click are horrid to use. The build of the entire unit is bad, the plastic feels cheap and the charging connector is over twenty years old (mini-b) so prepare to buy another cable or an adapter to use it with any existing chargers you have. Theres no touch screen and all of the buttons feel loose. The operating system isnt intuitive either. If you want to study for hours so you can figure out how to use this to study for hours, this cheap, hollow feeling plastic is for you. I can buy a cheap smartphone with more power, newer components, better build quality, several forms of wireless connectivity, an IPX waterproof rating, thats also compatible with my existing charging cables, that does an infinite amount more than this calculator. Lets not forget that this is Texas Instruments top of the line unit that came out on July 15th, 2019!!!. Let that sink in for a sec. Youre paying anywhere from $150 USD to $250 for a thing that in every way is worse than other options that are available to you, that are cheaper, and more robust with far more reusability and durability. Also, if you buy it new you get one copy of the digital version of the calculator. If you happen to have a computer at home and take a laptop to school youll have to pay the full price on the second computer (currently over $100) since they dont offer additional device pricing, like most software companies have, and good luck finding any information about pricing online. Its not even listed on their website. If you can find it, go with the HP Prime Graphing Calculator. Its discontinued, better in almost every way.

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.

This calculator has a million mathematical functions built in. Each day I learn a new feature that makes me appreciate this calculator more. It does factoring of polynomials, double and triple integrals all symbolic and numerical. No need for a separate financial calculator. This calculator has many financial functions built in. Also the built-in financial solver is beautiful. Overall, a great cal

Cant ever go wrong with a TI-Nspire. Ive used the normal TI-Nspire CX at school during all my 4 years in high school, so Ive become fairly comfortable with operating it. But, I felt it was time for an upgrade, so I chose this, and Ive got to say, best investment ever. As an engineering college student, this calculator really helps save time. With its CAS, solving integrals and taking complicated derivatives couldnt have been any easier. The buttons (arguably), in my opinion, feel very nice to click and make a satisfying clicking sound, which I like (compared to the normal CX). It has functions from solving systems, to analyzing statistical data, and you can even program your own functions using TI-Basic. All in all, this is definitely a must-buy for any college student taking high level engineering classes. One thing to note is that this (and many other CAS calculators), are not allowed on AP math exams. Also, as Im sure youve heard. graphing calculators are not allowed in lower college math classes either (ex: Cal 1, Cal 2, or even Cal 3). It is, however, allowed on the SAT and upper-level engineering/science courses in college, at least in my experience.

Cons: - Screen is painful to look at; poor anti-aliasing and blurring issues. - A touchpad that makes selecting anything a PITA without accidentally changing the selection. - An enter key that is awkwardly located far from the touchpad. - Math keys are fused into franken-buttons (one key with a dead-space between the sides). - Very poor tactile confirmation that a key is even being pressed. - Cheap Playschool plastic case. - Glued-on rubber anti-slip feet likely to fall off with any regular use. - Not as light as expected despite being thinner. - Trig functions and commonly used constants are found in menus rather than broken out into separate buttons. Inexcusable design choice. - Alphabet keys are, astoundingly, not in standard keyboard order despite being arranged like one. Everyone has a smart phone, why would you not copy that layout? - Despite the beefy processor specs, everything feels sluggish. Noticeable input lag. Pros: - If the screen werent so terrible, the operating system would look good. - Full fledged file handler and tab manager is pleasingly modern. - Its a python interpreter and advanced math engine in a calculator. Thats amazing. Final thought: - TI needs to fire their hardware people for designing that franken-button layout. If the four math keys most used feel like hot garbage, thats a pretty big issue. - The anti-aliasing needs serious reprogramming. No functionality can make up for a screen that causes immediate eye-strain. - Replace the touch-pad with a d-pad. Youd improve the interface and save a couple bucks per unit at the same time.
