Graphmatica - Qquation plotter with numerical features

Graphmatica is a powerful, easy-to-use, equation plotter with numerical and calculus features

Graphmatica is an equation plotter with easy to use controls for numerical and calculus features. Graphs 2-D Cartesian functions, relations and inequalities, plus polar, parametric and ODEs. Up to 999 graphs on screen at once. Offers copy to clipboard (bitmap/WMF/EMF), Button Bar, on-line help and demo files. Great for students or teachers of any level math from algebra through college calculus.

While it is designed to be extremely simple to use, its advanced features may not be readily apparent to the first-time user. Please take a moment to acquaint yourself with them:

In summary, Graphmatica is a great tool for students and teachers of anything from high-school algebra through college calculus.

Graphmatica features:

- The Redraw Queue. Graphmatica remembers up to the last 999 equations you typed in or loaded from a file. You can save your work for use in a later session or with any text editor.
- Advanced equation parser follows mathematical rules--not the computer's. You can use implied multiplication, a complete library of math functions (including trig), and even leave out those annoying parentheses in appropriate places. Forget about isolating variables before graphing! Graphmatica will isolate the dependent variable for you, if possible, and even graph many relations that can only be specified as implicit functions.
- Powerful graphing engine. You can choose between six styles of graphing: regular Cartesian, polar, parametric, and slope-field and initial-value approximations for up to fourth-order ODEs (and fourth-order linear systems as well), all detected automatically based on which variables you use in your equation. Cartesian inequalities are supported as well. Most graphs appear instantly on Pentium-class machines.
- Data plotting and curve fitting support make it easy to highlight points on a curve or enter experimental data sets and find the equation of best fit.
- Easy to use controls, including a toolbar, right-click popup menus, the status bar, which displays relevant information and help messages, and the Redraw Queue combobox, which lets you select any equation in memory to graph, delete, or edit to form a new equation.
- Pause and Point tables options let you see the coordinates of points on your graphs... as they are drawn. The Point tables show values at an interval and precision that you control, so you can get detailed numerical results or practice sketching curves yourself.

Requirements:

- Graphmatica supports high-resolution (e.g. 1024x768) video modes


Limitations:

- 30 days trial
