## Online LaTeX equation editor

Richard Hayes sent me this link to a nifty online LaTeX equation editor:

http://www.codecogs.com/latex/eqneditor.php

The best way to include maths in a wordpress.com blog (and lots of other places, such as Wikipedia) is using LaTeX, so this online editor should come in handy for anyone getting to grips with it. It shows you the fully formatted equation in real-time as you’re writing it. Also, it has buttons to add in a wide variety of mathematical symbols etc, which is useful for anyone not that familiar with LaTeX’s many commands and symbols.

I gave it a quick try myself and it seems very convenient. These are the equations I wrote in it – anyone recognise them?

$F(j\omega)=\int_{-\infty }^{\infty}{f(t)e^{-j\omega t}\textup{d}t}$

$f(t)=\frac{1}{2\pi}\int_{-\infty }^{\infty}{F(j\omega)e^{j\omega t}\textup{d}\omega}$

I added those equations into my WordPress post using the following code (typed / pasted into the main text of the post):

$F(j\omega)=\int_{-\infty }^{\infty}{f(t)e^{-j\omega t}\textup{d}t} &s=2$

$f(t)=\frac{1}{2\pi}\int_{-\infty }^{\infty} {F(j\omega)e^{j\omega t}\textup{d}\omega} &s=2$


Also, Eamos Fennell sent me a link to another similar site which seems pretty good:

Not sure if this site is down now (02/11/12) or if its just on my computer. Anyway, I found another site that does the same. Not as user friendly but it gets the job done. http://www.sciweavers.org/free-online-latex-equation-editor

Hi Eamos. It seems to be back online now, but I’ve added the one you suggested to the post anyway in case the first one disappears again. Thanks!
