Please note: This version remains available for those who need to add machines to an existing installation, or want functionality equivalent to the Windows 3.1 version, but the current version is 2.0.

• Long filenames
• Enhanced metafiles (note: you need Word 97 or up to paste these anywhere)
• Standard toolbar with color pictures and tooltips.

Feature overview:

1. The Redraw Queue. Graphmatica remembers the last 25 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 or Graphmatica 3.6 for DOS.
2. Automatic functions. Graphmatica will automatically
   • determine the type of graph you are entering based on the variables used,
   • recognize an equation's domain if you include one,
   • alter the sampling rate dynamically while graphing to make sure steep graphs like y=tan x are tracked correctly,
   • adjust the x/y ratio when you reset the range or change the size of the graph window so proper aspect ratio is maintained,
   • redraw the most recently-entered equation(s) when you change the size or shape of the grid by any means, and
   • restore the grid and special options settings when you load an equation list that has them.
   You don't have to do anything to use these functions, but the Options menu still gives you complete control over them.
3. 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! As long as there is only one instance of the dependent variable in the equation, Graphmatica will isolate it for you, and even graph relations. You also get the power of 6 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. Cartesian inequalities are supported as well.
4. Easy to use controls, including the convenient Button Bar which provides one-click access to the most frequently-used commands, 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.
5. Pause and Print tables options let you see the coordinates of points on your graphs... as they are drawn. Print tables shows values at whole-number intervals so you can practice sketching curves yourself.
6. Convenient mouse-oriented operations. You can use the mouse to select a new range or view the coordinates of a point, select the initial value for an ODE, and even find the tangent line of a curve or integrate a function without pressing a single key.
7. Flexible graph paper. Choose between regular graph paper and paper appropriate for trig, polar, and logarithmic functions, at four levels of detail.
8. Powerful symbolic and numerical calculus features. Find derivatives, integrals, and critical points for any Cartesian function.
9. Lots of output options. Graphmatica lets you copy equations, point tables, and graphs to the clipboard, and you can print your graphs in full color.
10. Every automatic option is also user-settable to give you absolute control over your graphs. The Options Settings dialog not only shows you the current settings, but also acts as a master control panel to let you change any customizable option from one dialog box. And the Save Setup Info command lets you save your preferences so they are automatically restored whenever you run Graphmatica.
11. Instructive help topics explain the basics of each type of graph...and included demo files show you examples of each form of equation.
