Description

This symbolic graphing calculator, sold by Texas Instruments, was introduced in 2004 as an improved version of the TI-89. The handheld electronic calculator has a black plastic case with a sliding cover that can also serve as a stand, and a silver plastic keyboard. It has an array of forty-one plastic keys of diverse shapes, many of which can take on three meanings. These include a wide number of arithmetic, trigonometric, statistical, algebraic, and analytic functions. Letters of the alphabet also can be represented. The calculator also has three arrow keys, plus a row of five keys immediately under the display that relate to graphing, tables, and preprogrammed functions. In addition to performing a wide range of calculations, the calculator could display text or icons. It also could display two-dimensional graphs of rectangular, parametric or polar functions simultaneously, either overlapping or on a split screen. Three-dimensional functions also could be shown. It also could list tables and calculate and display derivatives and integrals of functions.

A mark above the display reads: TI-89 Titanium (/) TEXAS INSTRUMENTS TI-89. A cable allowed sharing data with other instruments.

A mark toward the top of the back of the calculator reads: 2035034432 S-0604A. A compartment below this holds four AAA batteries as well as a small 303 CR or SR44SW backup battery. A mark inside the battery compartment reads in part: MADE IN CHINA. Further text indicates that the design was copyrighted in 2004.

Included with the calculator are USB and link cables, a manual, a CD with instructions, and two advertising sheets.
