[Xerte] Maths symboles

[Paul Swanson]

I don't know if it is a good solution, but OpenOffice supports MathML
and includes a Math Equation Editor. Also, the W3C's Amaya is mentioned
as a WYSYWIG MathML editor in Wikipedia. Both are free. I've never had
to work with MathML, so can't say how easy they would be for academics
to use.

	Also, the issue is how to allow people to easily enter / create
the expressions? Using this stuff is alright for developers, but how to
easily allow an academic to write out a calculus or matrix problem? This
is not a Xerte specific problem - very few tools have any ability to do
this. Has anyone come across a good solution? How have people dealt with
it before?

	You can display a pretty fair number of math symbols using HTML.
I just tested displaying the Sum (sigma) symbol, and infinity using
∞ and Σ, respectively, in Xerte and both symbols were
displayed. There are many more symbols available, but I only tested
those two. You have to use the numeric entity reference, the named
references don't seem to be supported.

		Funnily enough we have the same issue on a current
project. We want to develop content for engineering that needs to make a
lot of use of mathematical expressions. Currently the only way to do it
in Xerte is to use some other tool to render the expression and then
take a screenshot and use the image in Xerte. This is fine if the number
of expressions is relatively low, but in our case we'd like to
dynamically generate the expressions and render them at runtime. There
is no MathML support in Flash natively, and I've not found a good
component for rendering MathML or LaTeX that I could wrap. If anyone is
aware of a good MathML / LaTeX component, please let me know.

		How one can write mathematical expressions in a content
of a LO?
