This graphing calculator from Texas Instruments offers powerful numeric and graphing solutions for advanced mathematics, science and engineering coursework. Calculator has I/O port for fast, easy data sharing with TI-86 and TI-85; unit-to-unit link cable included. Other features include storage of 3 definitions of statistical plots; to create equation library to solve any variable; linear algebra capabilities for matrix algebra and matrix manipulation; computation of complex numbers in rectangular or polar formats; 90 different unit conversions to aid in problem solving; 24K RAM available and 160K user data archive/application memory. Connects to IBM or Macintosh for editing, storing and Graph Link cable/software battery included. 86. Imported.
Designed with power users in mind, the TI-86 graphing calculator has all the power and functionality of the popular TI-85 but with significant enhancements aimed at students of college mathematics, engineering, and science. The TI-86 includes a function evaluation table, deep entry recall, seven different graph styles with multiple line and shading options, and slope and direction fields for differential equations. In addition, the TI-86 boasts 96 KB of user-available memory--three times more than the TI-85. Theres also a new function evaluation table which shows numeric output for function, polar, parametric, and differential equation modes.
The TI-86 runs with programs designed for the TI-85 and includes all the same matrix features, but with a new matrix editor that allows the user to view and edit matrices in two dimensions. You can also view multiple lists and attach formulas to those lists for automatic computations. A new aspect of the TI-86 is the ability to customize product functionality with machine language programs downloaded from TIs Web site. Besides the strong graphing abilities, the TI-86 also has powerful calculus features like integration, derivatives, minimums, maximums, roots, and arcs. It also supports Z80 assembly language programming.
The 64 x 128 high-contrast pixel screen displays eight lines of 21 characters each plus two levels of display menus. With the TI-86, you can link to other TI-86s and TI-85s via the input/output port, and to CBLs, CBRs, and computers. --Dana Van Nest
