Usage is fairly complex but there is a nice tutorial here:

http://www.forkosh.c...extutorial.html

Use the following syntax:

[math]f(x)=\int_{-\infty}^x e^{-t^2}dt[/math]

...which yields

[math]f(x)=\int_{-\infty}^x e^{-t^2}dt[/math]

Alexander has written a hack that lets us use Latex to write equations.

I am actually having some problems with this.

We may be seeing some sort of caching problem.

I'm sure Alex will figure it out.

[math]E=mc^2[/math]

[math]E_k=1/2kx^2[/math] now i can use sub/superscripts

and intergrals.. [math]\int\arctan(x^2/y)[/math]

[math]\begin{\pmatrix}c&o&o&l&a&n&d&m&a&t&r&i&x&s\end{\pmatrix}[/math]

As a side note I'll mention that the forum also supports a [noparse][/noparse] tag so that example BBCode can be posted. This allows you to actually post BBCode code that can literally be copy and pasted like[ latex ]f(x)=int_{-\infty}^x e^{-t^2}dt[ /latex ]

[math]f(x)=int_{-\infty}^x e^{-t^2}dt[/math]. Perhaps someone will find this useful

OTOH, there appear to be some hiccups because it should be able to parse [math]f(x)=1[/math] and the parantheses seem to be hanging up. Maybe it's a syntax problem with this version though.

Yeah it's a little buggy apparently.

ok, so there is no workaround for this yet, so i will warn people and explain what is going on.

the mimetex plugin works very beautifuly, the problem is when it touches vbulletin, something crazy happens and this extremely weird issue comes up:

so apparently there is a problem with parsing bbcode, and for some reason or another, a parenthesie before the first equal sign it screws stuff up and breaks some links that does not allow the images to render at all...

so a workaround, not a solution, still working on that one:

\int_{a}^bf(x)dt=\sum_{i=1}^n f(\overline{x_i})\Delta x

does not work as demonstrated here:

[math]\int_{a}^bf(x)dt=\sum_{i=1}^n f(\overline{x_i})\Delta x[/math]

but you can use the same equation and write it as:

\sum_{i=1}^n f(\overline{x_i})\Delta x=\int_{a}^bf(x)dt

as i demonstrate here:

[math]\sum_{i=1}^n f(\overline{x_i})\Delta x=\int_{a}^bf(x)dt[/math]

similarly:

x=f\left(x\right) works

[math]x=f\left(x\right)[/math]

while the opposite f\left(x\right)=x does not

[math]f\left(x\right)=x[/math]

P.S. Reimann's sum demonstrates most crazy good effects of latex. if you want some code for matixees or complex fractions to refer to, i'll be more then delighted to write a tutorial for the math forum... that is if anyone needs it...

So now Q can do his sig with:

[math]\text{Qfwfq} =\\ \left(i \cancel{\partial} - m \right) \Psi = 0 [/math]

{with the extra "Qfwfq=" stuck in as a workaround for alex's bug...}

Qool!

it is a workaround, but i want it to work like it is supposed to, but that would work buffy...

Posted 04 May 2006 - 03:42 PM

probably could add that to the latex bb tag, to add names automatically, but still, i want it to work the way it is supposed to!

Posted 11 May 2006 - 08:15 PM

success, this actually finally works, its alive

Posted 12 May 2006 - 03:45 AM

Great job, Alexander!

ok, i think that this thread needs a little pointing, for those who are interested, i just finished a tutorial on Latex in the math section (sort of where its needed a bit more) so please dont hesitate and visit:

http://hypography.co...ath-v2-0-a.html

there is also a link to latex practice grounds thread, and if you have any questions, please, please post them in the linked stickey, i want people to be able to refer to a single thread for guidance... I dunno whether i should block this thread or something, but please go to the Physics and Math section for the latex stuff...

Really just getting started with this Latex and already I've discovered a problem. I understand how to show sqrt-root but how do I show cube-root or even higher powers of this function? Any help would be appreciated.....Infy

\sqrt[3]{X} renders as [math]\sqrt[3]{X}[/math]

Though there are many excellent LaTeX references, I usually refer to http://meta.wikimedi...ki/Help:Formula . I don’t think it’s complete, but it’s yet to fail to answer any of my questions.
