Intended for use with TI-84 Plus. TACULATOR 84 GRAPHING CALCULATOR • Your graphing calculator for high school and college students. • Includes all the commands and functions for advanced math, list, statistics, distribution, stat plots, etc. • Use the arrow keys or your fingers to navigate inside the app. • Covers everything you need: Pre-Algebra, Algebra 1 & 2, Pre-Calculus, Calculus, Statistics... IT'S EVEN BETTER THAN AN ACTUAL CALCULATOR • Taculator is 100X faster as it uses the huge calculation power of your iPhone/iPad, while handheld calculators are often slow. • High-resolution graphing window: Make sharp and beautiful graphs. • Your new calculator weighs nothing and is always ready on your phone. • Share your calculations with friends as a text message or email. ◉ Math Functions • Scientific calculator with all basic arithmetic and advanced functions. • Ability to scroll through history and copy previous calculations. • Complex numbers support • Probability functions like nPr, nCr, factorial, random numbers. • Enter fractions easily. • Convert angles and use DMS format. ◉ Graphing Functions • Graph every function you want and trace for X- and Y-values  • Calculate intersection, zero, minimum, maximum, integral, and derivative. • Switch between full-screen graphs and normal mode. • Zoom in and out with your fingers and adjust the window settings. • Graph statistical plots like histogram, box plot, scatter plot, xy-line plot • Draw vertical, horizontal, tangent, circle. ◉ Matrix Calculator • Store matrices and reuse them using shortcuts like [A], [B], [C],... • Do matrix arithmetic operations: Scalar multiplication, addition & subtraction, multiplication, power of a matrix. • Calculate transpose, determinant, dimension, inverse matrix, row echelon form, reduced row echelon form, identity matrix, cumulated sum. ◉ List, Statistics, and Distribution • Use the stat list editor to enter your list values. • Perform 1- and 2-Variable statistics. • Use lists to calculate min, max, mean, median, sum, product, standard deviation, variance. • Find best-fit regressions: LinReg (ax+b), LinReg (a+bx), QuadReg, CubicReg, QuartReg, LnReg, ExpReg, PwrReg, Logistic, SinReg. • Perform statistical tests: Z-Test, T-Test, 2-SampleZTest, 2-SampleTTest, 1-PropZTest, 2-PropZTest, ZInterval, TInterval, 2-SampleZInterval, 2-SampleTInterval, 1PropZInterval. • Calculate various distributions: Normalpdf/cdf, invT, Tpdf/cdf, χ2pdf/cdf, Fpdf/cdf, Poissonpdf/cdf, Binompdf/cdf, Geometpdf/cdf. ◉ Command Catalog & Syntax Help • Get help with all commands with our integrated Catalog & Help section.  • It provides you with syntax help, examples, and possible error messages. • Enter a command and the app will show you the right syntax next to the cursor.
