	FlatGraph  License: Freeware
	Plotting functions (usual and parametric) with more possibilities. Differentiation of any order (with simplification). Construction of tangents to the graph. The simple and clear interface with the detailed documentation and examples of work. The program is designed both for inexperienced and the professional user as in it are combined the intuitive interface and professional functions. FlatGraph allows: - To enter one or several functional expressions of any complexity for display and (or) their differentiation; - To carry out symbolical differentiation for the specified order of a derivative, and also to carry out simplification of the received derivative; - To investigate "alive" changing of various parameters of functions with simultaneous display of new graphs that allows to define influence of parameters of functions on their form; - To use automatic or manual scaling schedules of functions for linear scales; - To display parametric functions, for example, ellisoid, cardioid, Bernoulli lemniscate and other similar graphs (where abscissa and ordinate depend on one parameter 't'); - To solve the equations, system of the equations and inequalities by graphic way; - To define and display a tangent to the graph of function in a point x0 (it is set by the user). FlatGraph has the simple and clear interface, detailed user guide and examples of work. Author: Vitaliy Subbotin| Date: 19-01-2005 | Size: 567 KB

	Calc 3D Pro  License: Freeware
	Calc 3D is a collection of mathematical tools for highschool and university. The calculator can do statistics, best fits, function plotting, integration. It handles vectors, matrices, complex numbers, coordinates, regular polygons and intersections. For objects ( like point, line, plane and sphere) distances and intersections are calculated. Cartesian, spherical and cylindrical coordinates can be transformed into each other. Carthesian plot, polar plot, parametric plot, best fit, fast fourier transformation, histogram, smooth,...

	RF21  License: Freeware
	RF21 for Windows is a scientific calculator, plotter, programming and numeric system in one. It allows for permanent installation of a user's own commented functions and libraries. Such user functions may have one or several arguments and values. Works as an archive at the same time, with integrated searchable database, to let you find and reuse materials created years ago. Each function self-reassembles when its name is called, autonomously searching the libraries for all components needed. Predefined functions include gamma, zeta, psi and Bessel functions, error integral, cumulative Binomial distribution and more. On top of these and the user libraries, the program's numeric and plotting capabilities can be used, including: Numeric derivation and integration, Monte Carlo simulations, linear equations, matrix inversion and eigenvalues, nonlinear equation systems, n-dimensional function minimizer (Dennis & Schnabel method), Runge Kutta method for (systems of) differential equations, accelerated summation of series. Fraction reckognizer. Fast screenplots and an environment for designing printable plots, which may as well be exported to -.GIF and -.BMP files. Ample support for both simple and parametric plots, composition of several curves into one picture, drawing of directional or vector fields. Comes with standard libraries covering areas of science and mathematics. Some 200 standard functions, see author's homepage for a systematic reference of these.

	Sicyon Lite calculator  License: Freeware
	Sicyon is all-in-one scientific calculator for every researcher and engineer. The core of Sicyon is an expression (VBScript/JScript) calculator with features as: estimate a function using variables, user-defined functions and Sicyon objects; plot/tabulate a function; solve an equation, minimums, maximums and definite integral of a function; fit a function over data set; sophisticated units converter; database reader with various physical and chemical constants; matrix operations; set of plugin tools. Features ( marks the new ones for version 4)    - calculate the value of a math expression using variables and user-defined functions.  - easy access to user-defined functions (VBScript™ or JScript™ languages ) by buttons organized in function boards.  - 'Program mode' allows you to execute pieces of VBScript™ code in the main window.  - a board browser for easier access to the boards and their content.  - plot / tabulate a function in Explicit or Parametric mode.  - find real roots, minimums, maximums and definite integral of an expression in a given interval.  - curve fit over data (non-linear regression)  - customizable HTML reports for all math procedures.  - use a sophisticated units of measurement converter.  - search in tables with various physical and chemical constants arranged in data boards.  - editable spreadsheet-like user-data boards.  - use matrices and matrix calculations.  - "plug-in" additional applications called tool boards, usable as objects in the script.  - organize the boards as tabbed pages in groups .  - context information on each level of organization - function buttons/ boards/groups.  Advanced users can also:  - use the function boards in any VBScript™ or JScript™ for your web page or elsewhere.  - use Sicyon as out-of-process COM server to access a scripter and most of Sicyon's features (a development kit is include in the Pro and Plus versions)  - easily create new data boards with DataBoard Utility.  - add new units of measurement and their conversion rules from, and to SI.  Sicyon context sensitive help is always at your services.
