JsMath

This page is dedicated to jsMath, a javascript that allows to render LaTeX formula enclosed in $...$.

Install

Reference instructions:

• Install & testing
• Installing extra fonts

Server Side

• Install jsmath main package.
• Install extra fonts package for fonts msam10 and msbm10 (these fonts are required for extension AMSsymbols, which is frequently used).

The packages are found here. To install them, create a directory fonts in jsmath directory, and unzip them there, i.e. you should end up with 2 directories named ./jsmath/fonts/msam10 and ./jsmath/fonts/msbm10.

Client Side

• Install the standard fonts.

On Windows, the fonts are in package called TeX-fonts-25.zip (from this page).

On Linux, due to FireFox issue since v3.6, use the package TeX-fonts-linux.tgz (from this page).

• Install the extra fonts msam10 and msbm10 (from here), and install them on your system.

Troubleshoot

• I get the error message "unknown control sequence \msbm" when using \mathbb{...} (blackboard bold).

Most probably this is because jsmath cannot find the font definition file at ./jsmath/fonts/msbm10/def.js on the server side (see [1]). \mathbb uses the fonts msbm, and to work properly, the author package msbm10.zip (see here) must be unzipped in directory ./jsmath/fonts/. Also for best rendering the msbm10 truetype font should be installed on the client side.

Examples

Some text before <math>\textstyle{a_i^e}</math> and after

Some text before a_i^e and after

Some text before

a_i^e

and after

<math>\textstyle{ \frac{ \sum_{i=1}^n(x_i-\overline x) (y_i-\overline y) }{\left[ \sum_{i=1}^n(x_i-\overline x)^2 \sum_{i=1}^n(y_i-\overline y)^2 \right]^{1/2} } }</math>

<math>\displaystyle{ \frac{ \sum_{i=1}^n(x_i-\overline x) (y_i-\overline y) }{\left[ \sum_{i=1}^n(x_i-\overline x)^2 \sum_{i=1}^n(y_i-\overline y)^2 \right]^{1/2} } }</math>
