Graphmatica can help you plot mathematical equations. It can interact with the user to generate graphics representing algebraic curves. Despite the evident complexity of working with equations, you can easily visualize the graph of the desired equation, just by entering its algebraic form. This way, if you enter multiple equations, you can easily compare their graphic representations.
The application has a sober interface, which is typical of educational and scientifically-oriented software. Most of the main screen is devoted to displaying the graphics while a lesser part of it is occupied by the menu and the toolbar. You can generate graphics using six different styles: regular Cartesian, polar, parametric, and slope-field and initial-value approximations. It is a good thing that the program can detect the best style automatically according to the kind of variables used in a given equation.
Luckily, you do not need to type the same equation over and over, as the program can “remember” the last 999 equations you entered. The application also has an advanced equation parser, which eases its operation, because, instead of using computer rules, you can work with standard mathematical rules. Besides plotting equations, the program also supports various calculus operations, such as differentiating and integrating.
There are various ways to export or share the results of your work. The simplest method is to save your work using the program’s standard file type (*.graph), which you can later reload. Moreover, the application also supports clipboard operations, such as copy and paste. Likewise, curves can be exported as image files (BMP and EMF). Finally, you can print the equations, and it even lets you select your preferred color scheme. Unfortunately, although the help file states you can also save your work as a PDF document, the option was not available on my computer.
In general, Graphmatica is rather intuitive, although it definitely requires background knowledge on the part of the user. It can be an invaluable help for students and professionals alike.
