Edit detail for LaTeX revision 1 of 3

-
LaTeX ... is the world standard for writing technical documents.  Authors in
science and engineering are probably already familiar with it (or should be).
If you've wrestled with and cursed at "equation editors", you will love LaTeX.

What is most relevant for this site is *math*.  Citations are also under
development (but this will be physics specific initially, for me), see my TODO.
The following is borrowed from Winston Chang's "Latex cheat
sheet":http://www.stdout.org/~winston/latex/.

Math mode:

  To use math mode in-line with text, surround the equation with \$, like
  this !$x^2$ to make: $ x^2 $, or !\( x^2 \) or use !\begin{math} ...  \end{math}.  <br/>
  To make a block equation use !\begin{equation} ...  \end{equation} like this:

  \begin{equation}
    \int{x^2 + y_3}{dx}
  \end{equation}

  To make a block equation that is not numbered, surround the equation with \$\$, like
  this !$$x^2$$, or !\[...\] or use::

    !\begin{equation*}
    ...
    \end{equation*}

  like this:

  \begin{equation*}
    x^2
  \end{equation*}

Basic constructs:

\begin{tabular}{@{}l@{\hspace{1em}}l@{\hspace{2em}}l@{\hspace{1em}}l@{}}
\verb!^{x}!             &  Superscript$^{x}$ &
\verb!_{x}!             &  Subscript$_{x}$ \\
\verb!\frac{x}{y}!      &  $\frac{x}{y}$ &
\verb!\sum_{k=1}^n!     &  $\sum_{k=1}^n$ \\
\verb!\sqrt[n]{x}!      &  $\sqrt[n]{x}$ &  \\
\end{tabular}

Math-mode symbols (this is a subset):

\begin{tabular}{@{}l@{\hspace{1em}}l@{\hspace{2em}}l@{\hspace{1em}}l@{\hspace{2em}}l@{\hspace{1em}}l@{}}

Any other LaTeX environments work as well including array, tabular (the above
is tabular), and will be presented in HTML as an un-numbered block.

jsMath

  http://www.math.union.edu/~dpvc/jsMath

jsMath might be a good alternative to graphics for the
display of LaTeX, Axiom and Reduce output on the MathAction
wiki.

See for example
"jsMathExperiment":http://page.axiom-developer.org/zope/mathaction/jsMathExperiment
which contains some output generated by Axiom.

This might also be a good alternative to use with a
stand-alone browser interface to Axiom.

The jsMath package provides a method of including mathematics
in HTML pages that works across multiple browsers for both
Windows and the Macintosh. It overcomes a number of the
shortcomings of the traditional method of using images to
represent mathematics: jsMath uses native fonts, so they
resize when you change the size of the text in your browser,
they print at the full resolution of your printer, and you don't
have to wait for dozens of images to be downloaded in order to
see the mathematics in a web page. There are also advantages
for web-page authors, as there is no need to preprocess your
web pages to generate any images, and the mathematics is
entered in TeX form, so it is easy to create and maintain your
web pages.

For example:

http://moodle.org/ Moodle (course management software) uses jsMath

http://webwork.math.rochester.edu/ WebWork (Twiki-based) uses jsMath

It seems that jsMath doesn't work (i.e., display right) on Konqueror 3.1.4.

On up-to-date Fedora Core 3 (x86-64) with the ttf math fonts
installed, Konqueror 3.3.1-4.3.FC3 displays the in-line
(&lt;span&gt;...&lt;/span&gt;) overlapped with the text. The display
of the axiom output in (&lt;div&gt;...&lt;div&gt;) is ok, but it is not
centered as it is with FireFox. Firefox 1.0.4 on both Windows
XP and linux displays this correctly. IE 6 sp2 on Windows XP
also works fine.

This guy is way better at javascript and tex than me...

Couple comments on jsMath: http://www.math.union.edu/~dpvc/jsMath/

You are correct it doesn't work in Konqueror.

I gotta say I like this solution.  Putting the tex font metrics into the
javascript is very clever.  However he has the same problem I had in
identifying the font from javascript (i.e. you can't).  He looks at the
cmex10 font and checks if it is much taller than it is wide.  (This font
contains large parenthesis, for example)  Not 100% reliable, but
workable.  However using tex fonts one really needs to crank the font
size up so that the characters come out correctly.  For instance, $f(z)$
looks like $f(\approx)$ using their default font size.  Of course this
is easy to do on one's site.

Also since the rendering is done in javascript it is slow compared to
the native mozilla rendering speed.  I wonder if there is a way to get
it to render everything first, to prevent excessive reflows of the
document as it renders piece-by-piece.

The only drawback I can see other than speed is that it is not "true"
latex...for example he's got a \color extension, but no \usepackage...
or preamble of any kind.  So it's not appropriate for en masse
translation of an existing tex document.

But maybe very appropriate for a wiki...

With jsMath & Konqueror 3.3.2 (debian):

1. equations are not centered horizontally

2. certain characters are not appearing correctly (e.g. $x$ and the
    large left square bracket).  Both appear as a dot above the center
    line.

Other than that the output is almost correct.

Seems to work perfectly using Epiphany 1.4.4 on Fedora Core 3.

http://www.math.union.edu/~dpvc/jsMath/authors/welcome.html says to use:

&lt;disabled SCRIPT&gt; jsMath.ProcessBeforeShowing() &lt;disabled /SCRIPT&gt; 

which will prevent the page from being displayed until all
the mathematics has been processed. One reason to use this
is when the "flickering" involved in processing the mathematics
would be a distraction.
