Nspire Definition and 37 Threads

The TI-Nspire is a graphing calculator made by Texas Instruments which was released in July 2007. The original TI-Nspire was developed out of the TI PLT SHH1 prototype calculator (which itself was derived from the Casio ClassPad 300), the TI-92 series of calculators released in 1995, and the TI-89 series of calculators released in 1998. The TI-Nspire features a non-QWERTY keyboard and a different key-by-key layout compared to its predecessors. The TI-Nspire allows users to swap out the existing removable keypad with a functional copy of the TI-84 Plus series keypad. The TI-Nspire series I/O has a connector for the TI-Nspire Lab Cradle, another that serves as a connector for TI's wireless network adapter, and a Mini-USB connector for transferring data. The TI-Nspire series is available with and without a computer algebra system.
In 2011, Texas Instruments released the CX line of their TI-Nspire calculators which effectively replaced the previous generation. The updates included improvements to the original's keyboard layout, an addition of a rechargeable lithium-ion battery, 3D graphing capabilities and reduced form factor. TI got rid of the removable keypad with this generation and therefore, the TI-84 compatibility mode.
In 2019, the TI-Nspire CX II was added, with a boost in clock speed and changes to the existing operating system.

    Calculators RE- TI Nspire CX CAS vs Casio Classpad vs TI 89

    HI y'all! I was just told by my programming teacher that I need a new graphing calculator. She told me to decide between the TI 89, Casio Classpad fx-cp400 (or fx cp500) or the TI-Nspire CX C.A.S. I don't know if greyscale or color matters though in the long run. I am a programmer and need...

    Calculators Getting Fractions on TI Nspire CX - Eigenvectors & Polynomial Roots

    Hey so I'm new to my TI nspire cx, still getting the hang of it. I've been trying to figure out how to get my eigenvector values to be fractions instead of decimals when I calculate them on here. Also, when I find the polynomial roots I get back decimals instead of fractions. I would like to...

    TI Nspire CX CAS vs HP Prime vs Casio FX-CP400

    Hello everyone. I am going to be purchasing a good graphing calculator soon. That being said, I will hopefully be going to college to get a degree in aeronautical engineering. So what do you all think is the best of those calculators? I have been leaning towards the Casio CP400 because of the...
