There is a lite version? What restrictions does it have?
To Chase--My high school doesn't give out discounts on software to students (only teachers).
To jw2002--I know it works, but I just don't have $50 for even the academic version (I blew it all on iWork because Office 04 was really angering me).
XnavxeMiyyep--Can you just copy and paste the equations out of Grapher? I have used it before when I forgot my graphing calculator and it was very easy.
miles01110--I am trying out LaTeXIT as we speak
I have been familiar with
MathType for 20 years. I have never heard of
MathType Lite. The cut-down version of
MathType has always been named
Equation Editor. Versions of
EE have been bundled with
Microsoft Word and other word-processors and works apps for decades. Apple has chosen [what appears to be] the full version of
MathType 6 as the equation editor in
iWork 09.
As for
Grapher, its equation editing functionality is limited to closed-form explicit equations that can be used to draw 2-D and 3-D graphs. These are mostly of the form
y = f(x) and a limited selection of vector-matrix forms. As an equation editor,
Grapher is not even a poor substitute for
Equation Editor.
The OP wants a free equation editor. To the best of my knowledge,
LaTeXiT is his only choice. However, it is an excellent choice for a standalone free editor. Because
LaTeXiT requires a
teTeX installation, he should download and install
MacTeX. This will allow him to use the standalone
LyX word processor. Owing to its
TeX base,
LyX includes equation typesetting.
