Texas Instruments graphing calculator bundle TI-83 TI-82

Bundle & save on two Texas Instruments calculators! All used but still very functional (need batteries). Texas Instruments TI-82 & TI-83 are often required in high school math classes (algebra, trigonometry, statistics, pre-calculus, & more). They are made for graphing out mathematical & scientific problems & can connect to the computer for easy programming & data collection with the TI-Graph Link cable. 8-line x 16-character display plus a split-screen mode for reading graphs & viewing calculations at the same time. Analyze up to 5 matrix variables & save for later use. Includes functions for quartic polynomial regressions, intersections, & other common expressions. The TI-83 also includes function graphing, polar/parametric/sequence graphing modes, statistics, trigonometric, and algebraic functions, along with many useful applications. Apps & programs can be written on the calculator or loaded from external sources.
