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

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.

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

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

Muy útil para optimizar la resolución de procesos matemáticos, cuando tu objetivo no es evaluar tu habilidad matemática para resolver ejercicios, sino aplicar los resultados a un problema en específico como en el estudio de ingeniería. Diversidad de funciones, las cuales en muchos casos se pueden utilizar de manera intuitiva. Además de cálculos, permite trabajar con gráficas, las cuales en 2D tienen muchas opciones de análisis; por el contrario, las gráficas 3D si pueden quedarse limitadas cuando se desea trabajar en dicho espacio.

Llegó en buenas condiciones . Buen producto.

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.

This thing is amazing, I cannot say enough good things about it. As an aspiring engineer, its important to be able to check the accuracy of my calculations, and this calculator does it all. Theres a bit if a learning curve but thankfully plenty of resources on the internet to figure out what you need to in order to execute certain functions.

The TI-Nspire CX II CAS is a fast and powerful calculator with a CAS that, like the TI-89 Titanium, is fully integrated into the Scratchpad and Calculator app. Aside from CAS-specific functions, the user interface and menu trees are nearly identical to the TI-Nspire CX II. See my review of that model for more information.

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.

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.
