Ncalc - Graphing Calculator 84 與 Taculator 84 Graphing Calc 使用情況與統計

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.
