Graphmatica is curve plotting software designed for mathematical functions.

The Equation List. Graphmatica memorizes up to 999 equations typed or loaded from a file. You can save your equations for future use in Graphmatica, or with any text editor.
The command interpreter follows mathematical rules of priority—not those of the computer. You can omit the multiplication sign, use a complete library of functions (including trigonometric functions), and skip putting parentheses where they are not needed. No need to specify the variable! As long as your equation only has one variable letter, Graphmatica will recognize it and plot even implicitly defined relationships.
Overall, Graphmatica is a useful software for anyone who needs to plot mathematical curves quickly and efficiently.
