Texas Instruments TEXTI84PLUS Graphing Calculator

Product Description

The TEXAS INSTRUMENTS TEXTI84PLUS is a graphing calculator designed for students and professionals working through algebra, geometry, statistics, physics, chemistry, and biology applications. It ships with 480K of FLASH memory and 24K of RAM, giving it enough storage for preloaded apps and user-added programs. The built-in USB port and included TI Connectivity Cable allow straightforward data transfer to a computer or compatible device. An internal clock with date and time display supports timed tests and logging. Four AAA batteries power the unit, with a silver oxide backup battery that protects stored memory during a battery swap.

This calculator handles rectangular, parametric, polar, and recursive sequence graphing, making it a standard tool in secondary and post-secondary math and science coursework. The 8-line by 16-character display provides enough screen real estate for multi-step expressions. With 14 built-in zoom functions, users can inspect graph behavior across multiple scales without reprogramming. Preloaded applications cover core STEM subjects, reducing setup time in classroom and lab settings.
