i see you guys have the sigma symbol as the math code... i want to learn this code, because im quite confussed on how to learn it...
Go to this section of the forums. You will find tutorials on how to use LaTeX.
For example, if you type [tex]\sum_{k=1}^{\infty}\frac{1}{k^2}=\frac{\pi}{6}[/tex], you will generate the following image:
$\displaystyle \sum_{k=1}^{\infty}\frac{1}{k^2}=\frac{\pi}{6}$
If you'd like to see how someone coded the image, just put you cursor over the image and click on it. Then a pop up box will appear with the LaTeX code used to generate the image. You can try this out by clicking on my generated image.
