LaTex on the Forums
« on: December 23, 2011, 04:49:34 PM »
If you like to type in LaTex, simply surround your latex with dollar signs like: $ $ Hello World $ $

But make sure to remove the space between the dollar signs.

$$ \mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\, +\, 6\mathrm{O}_2 \,\rightarrow\, 6\mathrm{CO}_2\, +\, 6\mathrm{H}_2\mathrm{O} $$

Edit by Borek:

Site uses MathJax now. You can use [tеx][/tеx] tags for LaTeX equations, or [itеx][/itеx] for inline LaTeX:

For a polynomial [itex]ax^2 + bx +c = 0[/itex] roots take form

[tex]x_{1,2} = \frac {-b\pm\sqrt\Delta}{2a}[/tex]

where [itex]\Delta=b^2-4ac[/itex].

For formatting of single exponents and indices it is better to use [sup][/sup] and [sub][/sub] tags.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Strange. I have Java enabled and Mathjax works OK on my computer when I am browsing PF, but it doesn't work on CF. I wonder if it is not another Opera quirk.

Yes, I already checked that it works correctly under Chrome.

To make things more complicated this very thread doesn't display correctly to me when I visit it just following the standard thread link, but LaTeX was rendered right when I started to reply. Most likely it is something on my machine, but I can't reboot now to check if it helps.

I've also noticed it lags my machine when there is LaTex on the screen. It is why I didn't place any Latex code in my signature as before.

Yes, rendering LaTeX heavy pages can be time consuming, but I think it is worth it. Check for example this LaTeX tutorial that was prepared at PF.

.

And for inline math? I have just tried single dollars but does not work

Using single dollar signs is tricky, as they are often used just in text. As forum posts don't follow strict format of LaTeX document, it is impossible for MathJax engine to differentiate between $10 + $20 intended to mean $30, and $10$ that is intended to be an inline formula.

Edit: see http://www.mathjax.org/docs/1.1/tex.html for more details.

Thank you. I tried to modify the post, but passed the time limit. I have submitted another post with the parentheses delimiters and works. Please, feel free to delete the old post containing the dollars signs
