Introducing LaTeX Math Typesetting

In summary, Physicsforums.com has introduced the addition of LaTeX mathematical typesetting to their forum software. This professional-grade typesetting system allows for pleasing mathematical presentation and can be included in any post on the forum. Users can include LaTeX graphics by using the [ tex ]...[ /tex ] or [ itex ]...[ /itex ] tags, with the latter being used for inline graphics. The forum provides a pdf file and symbol reference for the most useful LaTeX commands, symbols, and constructs. The amsmath package is also available for more information. Examples of various techniques are provided, including subscripts, superscripts, and equations. Users can also use the [ tex usepackage= ] tag to include additional packages.

Why is that every time I write a math equation and when I click preview, I can never see the equation. I always just see the message telling me that the graphic is being generated. I have to submit my message first before I can see it. Can anyone please explain.

That's an error with the update, and Greg is working on it.

How do I insert a line break?

How do I insert a line break? I have read the pdf file explaining the different commands. I have tried the following:

\\
\ \
\\
\ \
\linebreak
\linebreak[4]
\linebreak[0]

and many others. All help would be appreciated.

You may want to try \begin{array} and \end{array} commands.
Click on my LaTeX image to see the code.
[tex]\begin{array}{l} \mbox{Text 1} \\ \mbox{Text 2} \\ \frac{x}{2} = \frac{\gamma + \beta}{\varepsilon} \end{array}[/tex]
This is covered in 3 .PDF files in the first post of this thread.

Is there a latex command for Feynman diagrams or contractions in QFT (the lines joining operators to denote propogators and things)?
 
  • #602
Hmm...I usually just delete and repost should any
problems with [tex]\LaTeX[/tex] previewing occur :shy:

[tex]\mathop {\lim }\limits_{n \to \infty } \bigcup\limits_{i = 0}^{n!} {\left\{ {\frac{i}{{n!}}} \right\}} = \mathbb{Q} \cap \left[ {0,1} \right][/tex]

In my last post I've written:

how can i write it using latex?
Page through this thread and you'll find several examples of integrals that you can copy.

Hmmm well, I thought I knew how, but now I'm not so sure. I'll have to look around. Maybe Ambitwistor knows a trick to put a command that has been \renew'd back to its default behavior.

Also, I found this pdf of useful mathematical constructs, that goes a bit beyond what we already have:

Let me try...

[tex]
\]
\usepackage{pstricks, pstcol, pst-text}

\begin{pspicture}(-4, -3.2)(3, 0.2)
\psset{linecolor=white} % hidden
\pstextpath
{\pscurve(-4, -2)(-2, 0)(0, -3)(2, -1)%
(3, -2)(5, -3)}
{\color{blue} % font color
If you want to type
$(a+b)^n=\sum_{k=0}^n {n\choose k}
a^{n-k}b^k$ and let it follow along
a curving line \ldots}
\end{pspicture}
\[
[/tex]
I think the problem is that a line like
"\usepackage{pstricks, pstcol, pst-text}"
may call packages that are unavailable to this system... or maybe it's that this line must come before the \begin{document} line, which we wouldn't have access to.

I think you'll just have to make do with the picture environment.
But one can get it to do some interesting stuff...

I am not familiar with drawing in LaTeX, and I just wonder where I can find a short tutorial on this topic.
I think it should also be added to the first page of this thread, so that someone new to LaTeX can learn how to draw.
It's just my $0.02.

I don't know of anyone else who uses this \picture environment here at PF. For general (i.e. not-necessarily PF) LaTeX, you might look at http://www.eng.cam.ac.uk/help/tpl/textprocessing/teTeX/latex/latex2e-html/ltx-43.html [Broken]

Here what I use sometimes http://jpicedt.sourceforge.net/
With some effort (see example below [click on image for source]) and some manual tweaks, you can get its output into a PF post.
