Pre-Owned Texas Instruments TI-84 Plus Graphing Calculator, High School and College, Split-Screen Display

Approved for the SAT, ACT, PSAT/NMSQT, AP, and IB exams, the Texas Instruments TI-84 Plus is a graphing calculator that students carry into testing rooms with confidence. The MathPrint feature displays fractions, exponents, and equations in proper textbook notation, helping students enter expressions accurately and verify their work. The 8-line display with adjustable contrast shows clear text in any lighting, and 480 KB of Flash ROM stores over a dozen preloaded applications for algebra, geometry, statistics, calculus, inequality graphing, and science data collection. Split-screen mode shows graphs and data tables side by side, and graphing covers function, parametric, polar, and sequence modes with 14 zoom features for detailed exploration. Statistical tools include 10 regression models, 6 plot types, 15 probability distributions, 9 hypothesis tests, and 6 confidence intervals. Matrix operations handle inverse, determinant, transpose, and row echelon form. An interactive equation solver lets students isolate and solve for any variable. The calculator runs on four AAA batteries with a backup for memory protection. From algebra through AP Calculus, this is one calculator for every class and every exam.

• Building on the hugely popular TI-83 Plus, which is perhaps the best-selling calculator of all time, the TI-84 Plus is completely compatible with its predecessor. From that well-established platform, this new model adds more speed (a processor that s 2.5 times faster), more memory (24 KB RAM and 480 KB of Flash ROM), an enhanced high-contrast display (eight lines by 16 characters), and more beloved Apps. It also adds USB on-the-go technology (cable included) that can be used to share files with other calculators or to connect to PCs or optional presentation tools. Twelve Apps are pre-loaded, including Cabri Jr., CBL/CBR, Conic Graphing, Inequality Graphing, Probability Simulations, Science Tools, StudyCards, TimeSpan, Topics in Algebra 1 Chapter 5, Topics in Algebra 1 Chapters 1-4, Transformation Graphing, and more. For students in math and sciences, the TI-84 Plus is a powerful, problem-solving tool with features for storing, graphing, and analyzing up to 10 functions. Plus, it displays graphs and evaluates tables on a split screen, allowing you to trace the graph and scroll through table values simultaneously. With the TI-84 Plus, you can view an equation, its graph, and the coordinates all at one time. Jump from point to point by entering a number. Several useful plot types are available, including scatter, box-and-whisker, XY-line, histogram, and normal probability plots. Advanced statistics and regression analysis, graphical analysis, and data analysis are readily accessed, along with features for calculus, engineering, financial, logarithm, trigonometry, and hyperbolic functions--all crucial tools for advanced analysis. With its clear display and fast processing, the calculator incorporates graphing tools for mathematics and science course work, including statistics and finance. The TI-84 Plus is powered by four AAA alkaline batteries (not included) and one silver oxide battery (included) for backup, with an automatic shutoff to save energy. It also comes with a hard normal slide case and is supported by a one-year limited warranty.
