Taculator 84 Graphing Calc

Taculator 84 is a graphing calculator and scientific calculator for high school and college math, intended for use with TI-84 Plus, CE, Evo and TI-83 on Android phones, tablets, and Chromebooks. Work with functions, tables, lists, statistics, and matrices using the commands and menus students and teachers use in class.

Math and entry

• Scientific calculator with every basic and advanced math function.

• Textbook-style fractions and mixed numbers, with exact answers as n/d or Un/d.

• Scrollable calculation history: tap any previous entry to copy or reuse it.

• Complex numbers (rectangular and polar), probability (nPr, nCr, factorial, random), and angle modes (degree, radian, gradian, DMS).

• Piecewise functions, list arithmetic, seq(, ΔList(, and augment(.

Graphs and tables to use with TI 84 Evo

• Four graphing modes: Function, Parametric, Polar, and Sequence, with trace, tables, Calc, and zoom in every mode.

• Smart trace snaps to zeros, maxima, minima, intersections, and asymptotes.

• Calc menu: intersection, zero, minimum, maximum, integral, and dy/dx derivative.

• Zoom tools (ZBox, ZSquare, ZTrig, ZoomFit) and drawing tools (text, pen, points, tangents, circles, shading).

• Split-screen view with graph and table side by side, plus statistical plots (histogram, box plot, scatter plot, xy-line).

Lists, statistics and distributions for TI 84 users

• Stat list editor with 1-variable and 2-variable statistics and input wizards.

• List math: min, max, mean, median, sum, product, standard deviation, and variance.

• Regressions: LinReg (ax+b), LinReg (a+bx), QuadReg, CubicReg, QuartReg, LnReg, ExpReg, PwrReg, Logistic, and SinReg.

• Hypothesis tests and intervals: Z-Test, T-Test, 2-Sample Z and T tests, 1- and 2-PropZTest, Chi-square tests, ANOVA, and Z and T intervals.

• Distributions: Normal, Student-t, Chi-square, F, Poisson, Binomial, and Geometric (pdf, cdf, invT) shaded on the graph.

Matrices, built-in apps and programs

• Matrix calculator: store matrices as [A], [B], [C] and compute transpose, determinant, inverse, ref, rref, row operations, and identity.

• Finance app with TVM solver, NPV, IRR, and amortization.

• Polynomial Root Finder, Simultaneous Equation Solver, Numeric Solver, Conics, Transformation, and Inequality Graphing.

• Write and run calculator TI 84 Basic programs, browse the searchable command catalog with syntax help at the cursor, and use physical keyboards on Chromebooks and tablets.

Made for students and teachers

• Pre-Algebra, Algebra 1 and 2, Precalculus, Calculus, and Statistics.

• SAT, ACT, AP Calculus, and AP Statistics exam prep.

• Students coming from a TI 84 or TI84 Plus Evo in class, and their teachers.
