There’s an excellent program called mimeTeX that renders math without a TeX installation. I used it with Drupal and DruTeX. Now I’m not using Drupal… so I need to find another way to display math.  Oh, mimeTeX still works, but you have to explicitly encode the link.  I’m way too lazy to do that.

Update: I’ve been experimenting with using [ tex ]…[ /tex ] from the mimeTex plugin to WordPress. It’s working now, but I needed to do two things to make it work.

• Create a cache folder under my wp-content folder.
• Modify the plugin to point to my local installation of mimetex.cgi.

I also had to go into the cache folder and delete all the files that were created during the process, so I could see the effect of the changes. But now it works!

Here’s an example of an equation array. Note that you need to use & to insert the required ampersand delimiters.

[tex]\begin{eqnarray}
\overset{*}{\triangleright}\!(uvx) & = & \triangleright\!(\overset{*}{\triangleright}\!(uv)x) \\
& = & \triangleright\!(\overset{*}{\triangleright}\!(\overset{*}{\triangleright}\!(u)v)x) \\
& = & \overset{*}{\triangleright}\!(\overset{*}{\triangleright}\!(u)vx)
\end{eqnarray}[/tex]

[ tex ]\begin{eqnarray}
 \overset{*}{\triangleright}\!(uvx) & = & \triangleright\!(\overset{*}{\triangleright}\!(uv)x) \\
 & = & \triangleright\!(\overset{*}{\triangleright}\!(\overset{*}{\triangleright}\!(u)v)x) \\
 & = & \overset{*}{\triangleright}\!(\overset{*}{\triangleright}\!(u)vx)
 \end{eqnarray}[ /tex ]

So… shouldn’t everyone just install LaTeX by default? Shouldn’t all CMS ship with some math solution? Of course!
