Pre-Owned Texas Instruments TI-83 Plus Graphing Calculator, Black, High School

The Texas Instruments TI-83 Plus delivers 24 KB of RAM and 160 KB of Flash ROM in a programmable graphing calculator that supports downloadable applications, custom programs, and data storage for math and science coursework. It is approved for the SAT, ACT, PSAT/NMSQT, AP, and IB exams. The 64 x 96 pixel LCD renders 8 lines of 16 characters each with adjustable contrast, and horizontal and vertical split-screen options allow simultaneous viewing of equations and graphs. Flash ROM technology means the operating system and applications can be updated and expanded over time, extending the useful life of the calculator. Graphing capabilities include 10 rectangular functions, 6 parametric expressions, 6 polar expressions, and 3 recursive sequences, with 14 zoom features and 7 graph styles for detailed visual analysis. One-variable and two-variable statistical analysis comes with 10 regression models, 15 probability distributions, 9 hypothesis tests, and 6 confidence intervals. Matrix operations handle inverse, determinant, transpose, and row echelon form for up to 10 matrices. It runs on four AAA batteries with a lithium backup cell that preserves RAM contents during battery changes. For high school and college students and educators who want a programmable, expandable calculator, this model delivers proven capability.
