【實用教育app】GraphNCalc83|最夯免費app

GraphNCalc is a full featured scientific graphing calculator featuring:

Algebraic entry: Enter problems using full algebraic notation. The command line editor includes interactive parenthesis matching and high lighting, undo and redo, bubble function help and a 200 level calculation history and recall stack. Generate a PDF report of calculations for mailing or printing using the SEND function.

Math functions: Trigonometry, logarithms, function minimum, maximum, numeric integration and derivatives, general solver, real and imaginary numbers, combination, permutation, random number generation, normal, T, chi squared, Fisher, poisson and geometric distributions, binary shift and rotate, test and logic operations, list operations including sort, std. deviation, sum, sequence, matrix determinant, transpose, sum, ref, rref, addition, multiplication.

Graph functions, parametric and polar equations and statistics plots: Full color graphs with touch to trace, pinch zoom, function minimum, maximum, intersections, asymptotes and numeric integration. All graphs can be output as a high resolution PDF file for mailing or printing. Interactively explore function behavior using variables tied to slider bars.

Statistics, Inferential Statistics and Distributions: A set of inferential statistics worksheets and graphs of distributions are included. The regression analysis screen allows you to quickly compute, view and analyze a data set using a variety of curve fitting methods.

Table: Analyze functions using the table viewer. Use the split screen mode to simultaneously view a graph and table.

Matrix and Lists: Matrix and list editors and a full set of matrix and list operations are built in.

Unit Converter and Constants: Convert between a wide variety of scientific, engineering and common units. A large set of physical constants are also included.

BASIC programming: Create, edit, debug and run BASIC programs. An interactive debugging screen allows you to set break points, single step and view program variables. Programs run more than 500 times faster than traditional calculators.

Chemistry: The calculator includes a full featured periodic table, a mass calculator and a data base of element properties. The touch interface allows you to view and interact with the periodic table to view by series, state, melting point, boiling point, electronegativity, electron affinity, valence, ionization, radius, hardness, modulus, density, conductivity, heat and year discovered.

Geometry: The geometry application computes perimeter and area for a variety of 2d geometric figures including squares, rectangles, parallelograms, triangles, polygons, circles, arcs and ellipses. A full triangle solver and interactive unit circle grapher are built in. Solve line intersections, project a point to a line and find a circle given 3 points.

Finance: Compute time value of money problems including annuities, lump sums and uneven cash flow analysis with IRR and NPV

Built-in user guide: A user guide is included and is always a touch away for handy reference. All functions have a full manual page with description of arguments and examples of use. Pop up bubble help displays function arguments during problem entry and program editing.
