LaTeX Online Equation Editor

Here is a neat website I found : http://www.codecogs.com/components/equationeditor/equationeditor.php

It allows you to type in a LaTeX expression and it generates a .gif file for you.

You can also use the following url to generate LaTeX notations on the fly:

http://latex.codecogs.com/format.latex?equation

where format is the ouput-format and equation is the the actual expression.

These are the available formats:
• gif
• png
• pdf
• swf
• emf
• svg

Here is an example with the following expression (format: gif) :

A=4r\int_0^r \sqrt {1-\frac{x^2}{r^2}}\, dx = 4r\int_0^{\pi/2} r\sqrt{1-\sin^2 \theta} \cos \theta\, d\theta

generates this:

$A=4r\int_0^r \sqrt {1-\frac{x^2}{r^2}}\, dx = 4r\int_0^{\pi/2} r\sqrt{1-\sin^2 \theta} \cos \theta\, d\theta$
