CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting.

DataFit is a tool used to perform nonlinear regression (curve fitting), statistical analysis & data plotting. Fit equations with up to 100 parameters to data with up to 20 independent variables. Define your own equations or choose from over 600 pre-defined equations. Results include customizable 2D/3D plots, as well as detailed fit information. Export code in BASIC or C to use an equation in a user written program. Easy to learn and use.

A free mathematical puzzle where equations are all mixed up. One solution per puzzle. Find the correct equations to solve the puzzle. Equations go in all directions - follow the arrows.

Graphing scientific calculator allowing for permanent installation of a user's own commented functions and libraries. It's also an archive capable of holding a lifetime's mathematical work. Integrated searchable database. Numeric features include derivation, integration, Monte Carlo simulations, Runge Kutta, matrix inversion, nonlinear equation systems, function minimizer. Prints plots and exports them to the -.GIF file format.

NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted. NLREG includes a programming language similar to C that you use for describing the function to be fitted. Two dimensional line and three dimensional surface plots can be generated.

IO Software Equations is the advanced equations editor which combines the power of features with use simplicity. Supporting over 700 symbols with more than a thousand possible combinations, equation library, real time Visual and LaTex editing, using its own scientific fonts, a fully configurable Speed Bar for fast symbol access, Equations! can be used as standalone or together with any applications supporting OLE, such as MS Office, OpenOffice.

LAB Fit is a software for Windows developed for treatment and analysis of experimental data. At LABFit you are able to:

1) Treat similar data;
2) Treat non-similar data;
3) Determine propagated error;
4) Plot 2D and 3D graphs;
5) Execute math calculations (system of equations, roots of function, etc);
6) Curve Fit (almost 500 functions at the library, with 1 and 2 independent
variables, functions finder, rejection of data).

The program PEEI calculates a discrete, numerical and approximate solution of a generic differential analytical model (i.e. a system of partial differential equations).

Unique interactive multimedia Chemistry teaching software that tests students as they learn. Topics covered include: elements, atoms and molecules, word equations, chemical symbols, Periodic Table and chemical formulas. Plus interactive simulations to teach the balancing of chemical equations and the formulas of ionic compounds. Written for use in schools, but an excellent personal tutor for anyone beginning to study Chemistry.

MathWriter is a stand-alone program that allows for the production of, Mathematical, Scientific and Engineering equations and formulae.Schoolteachers and Lecturers will find MathWriter useful for producing notes, reports and test papers. The program is designed so that an expression may be written on the screen and then translated into a bitmap image of required size. This image may then be subsequently imported to Microsoft Word.
