What is Ti-84: Definition and 65 Discussions

The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is an enhanced version of the TI-83 Plus. The key-by-key correspondence is relatively the same, but the 84 features some improved hardware. The archive (ROM) is about 3 times as large, and CPU about 2.5 times as fast (over the TI-83 and TI-83 Plus). A USB port and built-in clock functionality were also added. The USB port on the TI-84 Plus series is USB On-The-Go compliant, similar to the next generation TI-Nspire calculator, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the serial link port.

    Calculators TI-83/84 Plus - Storing polynomial functions

    Unless I'm missing something here, I've noticed that if you want to store a polynomial function on the TI-83 or the TI-84 Plus, you have to create a program that asks you what the value of x is, then displays the value of f(x). I kind of wish I could define a function without making a program.
