What is Nspire: Definition and 37 Discussions

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...
