Math Graphing Tool GrafEq Updated

Pedagoguery Software has updated GrafEq to version 2.10. GrafEq is a tool designed to help graph mathematical equations and formulae. The new version includes a French interface option, speed improvements, and new features. According to Pedagoguery Software:

GrafEq 2.10 for the Macintosh is now available (June 5 2001) for download. The previous version was GrafEq 2.09, released December 8 1999.

Changes since the previous version:

  • A French language interface is now available.
  • Considerable speed-up in sub-pixel verification. For example, y=log(x+1) completes graphing in seconds with GrafEq 2.10 instead of minutes with GrafEq 2.09. (With a 512 x 512 view over [-10,10] x [-10,10] running on a G3/300.) If this graph seems trivial, try it with another graphing program and see what it does...
  • Better graphing of formulae containing common sub-expressions, especially when discontinuous operators are involved: see for an example.
  • Exported views can now be exported as JIF or PCX files. See for more information about JIF.
  • Rich Text Format (RTF) encapsulation of formulae is now supported; this can help word processors vertically place formulae exported via the clipboard.
  • (Macintosh Version) Support for colour printing using an ImageWriter dot-matrix printer with a special colour ribbon has been removed. This legacy feature is rarely used; current colour printers (where the colour separations are handled by the MacOS in conjunction with the printer and its drivers) are still supported and produce much better output.

(GrafEq is a graphing utility that mathematically proves its generated graphs are correct and can subsequently reliably graph a wider range of formulae than any other graphing program.
