[Blindmath] mathplayer, jaws, and math in graphics?

[Sarah Jevnikar]

Hi Kevin and all,
If you install the math player plugin, open the attached file in IE and ok
any security warning you may get, you should be able to read a stats lecture
of mine from last term in Math ML.

As for LaTeeX output, check out this article on the Pythagorean Theorem from
Wikipedia.

http://en.wikipedia.org/wiki/Pythagorean_Theorm

The c squared = a squared + b squared formula is written in LaTeX.

hth,
Sarah

Hi Dr. Stacey,

I very much  appreciate the clarification on roles of MathML and LaTeX.
If I may, I have a few more questions.
* MathML output is only accessible with MathPlayer, which works with
Internet Explorer and JAWS. Is that correct? So, there's nothing for
Firefox or NVDA?
* What are commonly  used converters for LaTeX, which will get it
processed into a suitable format to be read?

I'm very interested in examples of MathML and LaTeX output.

Thanks,

Kevin
