## Description

Taculator 84 is a graphing calculator and scientific calculator for high school and college math, intended for use with TI-84 Plus, TI-84 Plus CE, 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  
• 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  
• 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 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, TI84 Plus, TI-84 CE, TI-83 Plus, or TI84 Evo in class, and their teachers.
