DeadLine License: Freeware
|
|
| |
DeadLine is an useful program, especially as an educational support, offering visual indications about the number of roots of an equation and a very precise estimation of those roots. The program solves equations graphically and numerically. It displays the graph of the function and a list of the real roots of the equation. It also includes the option to evaluate the function and its derivative. You can save the results provided by DeadLine and even create projects for future use. Although there is no flawless method for solving equations, the program combines four of the most successful methods in order to deliver you the right answer. And if you don't believe it's true, locate the roots on the graphic and convince yourself. No more problems on getting your homework done. Solve your problems in just a sec. It's easy and, best of all, free. Plus, you get a special gift.

Metalogic Calculator License: Freeware
|
|
| |
This calculator allows natural entry of equations (i.e. 17-(9*8) - 7 + 34.23). Then it goes beyond just giving you a result, the "steps" box, shows you how it solved the equation step by step. Results are given simultaneously in dec/hex/oct/bin. Great for students and home use. It takes the mystery out of solving complex equations.

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.

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.
