content: This is an example of an early graphing calculator sold by Texas Instruments. The TI-82 was introduced in 1993, as an improvement on the TI-81. The handheld electronic calculator has a gray plastic case with a sliding cover that can also serve as a stand. It has an array of forty-one rectangular plastic keys, 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 four arrow keys, plus a row of five keys immediately under the display that relate to graphing. Four of these also can take on two meanings. In addition to performing a wide range of calculations, the calculator could display eight lines of text sixteen characters long or graph ten rectangular or six parametric or polar functions simultaneously. It also could list tables and calculate derivatives and integrals of functions.
