Subject: GrafEq 2.10 PPC - Mathematical relation graphing software
Here is a fully-functional evaluation copy of GrafEq 2.10 PPC, a
program for graphing, and exploring, mathematical relations. It is
designed to be used for learning and teaching high school math.
Some of the new features: (for 2.10)
* A French language interface is now available.
* Sub-pixel computations are now performed using a multi-grid / recursive
method instead of a regular grid / iterative method (with progressively
finer grids / step-sizes). For some common graphs, such as y=logx over
[-10,10] x [-10,10], verification efficiency has consequently improved by
several orders of magnitude.
* Better graphing of formulae containing common sub-expressions, especially
when discontinuous operators are involved: see
http://www.peda.com/grafeq/gallery/decimal_squares.html
for an example.
* Rich Text Format (RTF) encapsulation of formulae is now supported; this can
help word processors vertically place formulae exported via the clipboard.
* Exported views can now be exported as JIF or PCX files. See
http://jeff.cafe.net/jif for more information about JIF.
