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.
• Navigate with the arrow keys or your fingers.
• Covers everything you need: Pre-Algebra, Algebra 1 & 2, Pre-Calculus, Calculus, Statistics...

IT'S EVEN BETTER THAN AN ACTUAL CALCULATOR
• 100X faster than a handheld — it uses the full calculation power of your iPhone/iPad.
• High-resolution graphing window for sharp and beautiful graphs.
• Weighs nothing and is always with you.
• Share your calculations as a text message or email.

◉ Built-in Apps
• Geometry: points, lines, circles and polygons — measure, transform, animate.
• Polynomial Root Finder & Simultaneous Equation Solver.
• Finance: Time-Value-of-Money solver, NPV, IRR, amortization.
• Probability Simulation: toss coins, roll dice, pick marbles, spin spinners, draw cards.
• Science Tools: sig-fig calculator, unit converter, data/graphs wizard, vector calculator.
• Transformation Graphing, Conics, Inequality Graphing, Periodic Table.
• Numeric Solver: solve any equation for any variable.

◉ Math Functions
• Scientific calculator with all basic arithmetic and advanced functions.
• Scroll through your history and copy previous calculations.
• Complex numbers support
• Probability functions like nPr, nCr, factorial, random numbers.
• Enter fractions easily — and tap any result to flip between fraction and decimal.
• Piecewise-defined functions, sequences and list commands like seq(, ΔList( and augment(.
• Degree, radian and gradian angle modes, DMS format.

◉ Graphing Functions
• Graph every function you want and trace for X- and Y-values.
• Smart trace detects zeros, maxima, minima, intersections and asymptotes as you move along the curve.
• Calculate intersection, zero, minimum, maximum, integral, and derivative.
• Full ZOOM menu: box zoom, presets like ZSquare, ZTrig and ZoomFit, zoom factors and zoom memory.
• Draw on your graph: text, pen, points, pixels, tangents, circles and shading — with colors and line styles.
• Store and recall pictures, or put a photo behind your graph as a background image.
• Graph statistical plots like histogram, box plot, scatter plot, xy-line plot.
• Full-screen mode, pinch to zoom, and complete window and format settings.

◉ Matrix Calculator
• Store matrices and reuse them as [A], [B], [C], ...
• Matrix arithmetic: scalar multiplication, addition & subtraction, multiplication, powers.
• Transpose, determinant, dimension, inverse, row echelon form, reduced row echelon form, identity matrix, cumulated sum.

◉ List, Statistics, and Distribution
• Enter your values in the stat list editor and run 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, PropReg, RecipReg, eBASEReg — with r and r² diagnostics.
• Perform statistical tests: Z-Test, T-Test, 2-SampleZTest, 2-SampleTTest, 1-PropZTest, 2-PropZTest, ZInterval, TInterval, 2-SampleZInterval, 2-SampleTInterval, 1PropZInterval.
• Distributions: Normalpdf/cdf, invT, Tpdf/cdf, χ2pdf/cdf, Fpdf/cdf, Poissonpdf/cdf, Binompdf/cdf, Geometpdf/cdf — and shade them right on the graph.

◉ Command Catalog & Syntax Help
• Integrated Catalog & Help for every command.
• Syntax help, examples, and possible error messages.
• Type a command and see the right syntax next to the cursor.
