Here's a site like Moo's, but its in english.

LaTeX

I wasn't able to use \iint on the french site, so I googled online latex converters and found this one.

However, when you input your code, you will need this [otherwise, it won't compile the code]:

Code:

\documentclass[12pt]{article}
\pagestyle{empty}
\usepackage{amssymb,amsmath}
\begin{document}
\[
[code goes here]
\]
\end{document}

For example,

Code:

\documentclass[12pt]{article}
\usepackage{amssymb,amsmath}
\pagestyle{empty}
\begin{document}
\[
\nabla ^2 = \frac{1}
{{r^2 }}\frac{\partial }
{{\partial r}}(r^2 \frac{\partial }
{{\partial r}}) + \frac{1}
{{r^2 \sin \vartheta }}\frac{\partial }
{{\partial \vartheta }}(\sin \vartheta \frac{\partial }
{{\partial \vartheta }}) + \frac{1}
{{r^2 \sin ^2 \vartheta }}\frac{{\partial ^2 }}
{{\partial \phi ^2 }}
\]
\end{document}

outputs

If you have mathtype, you can life a little easier. Type your equations there, and make sure when you copy it, it copies the latex code! [to get this to happen, go to **Preferences**-->**Translators...** Now select **Translation to other languages (text)** and in the scroll down [translator] box, select **TeX--AMS-LaTex**. Leave the two boxes at the bottom unchecked. Then click Ok].

Also, when you go to compile the code, be sure to check the box that says **Create URLs for the created image and the LaTex source. Using this option will save the image and the source permanently on the server.**

EDIT: Here's another example:

Code:

\documentclass[12pt]{article}
\usepackage{amssymb,amsmath}
\pagestyle{empty}
\begin{document}
\[
\iint\limits_R {f\left( {x,y} \right)dA_{xy} } = \iint
\limits_S {f\left( {x\left( {u,v} \right),y\left( {u,v}
\right)} \right)\left| {\frac{{\partial \left( {x,y} \right)}}
{{\partial \left( {u,v} \right)}}} \right|dA_{uv} }
\]
\end{document}

outputs
