There are a lot of interesting variations posted, maybe PF could have our own contest!

I wrote my first LaTeX like this:
... it was easy to calculate that
$$ ê^1=\hat x - \frac { \hat y } {\tan \alpha} $$
and
$$ ê^2=\frac { \hat y } {\sin \alpha} $$
where ...
Is it possible to make the vertical separation smaller? The first example in the latex primer does not seem to suffer...
The support for ##\LaTeX## is great, but there's just one thing I don't like: if I put a newline after the closing \$$ I get too much vertical space after the rendered part. For instance:
$$(x_1+\ldots+x_p)^n = \sum_{c_1+\ldots+c_p=n} \frac{n!}{c_1!\cdots c_p!}x_1^{c_1}\cdots x_p^{c_p}$$
As you...
The web pages at PF include this script, which won't load, so latex is not rendered:

Can anyone help? What is the convention for inserting the vector symbol?
I have a draft with -(\vec{2.5})^2 which displays correctly in preview
##-(\vec{2.5})^2\\##
why is vec troublesome and underlined in red?? Should I ignore!
I realise that I'm not using a variable.
Anyone recognise this problem?
When looking at posts with (presumably) Latex formulae, I get [Math Processing Error] instead of the formula.
It looks like everyone else can read them ok and even stranger, I sometimes see the formula for a brief moment before it is replaced by the message...
Hello everybody. My name's Laurent and I'm new in this forum. I wanted to say that the book "The theoretical minimum" by Leonard Susskind and George Hrabovsky is very good for students, amateurs or professionals. For talking about corrections of exercises, can I use Latex in this forum ? If yes...
Hello, this is my first question on Physics Forums and is a question on how to ask questions.
I have been using LaTex for a while already.
I wanted to post a thread about classical field theory. I tried to use \newcommand just to make easier the typing of expressions such as...

Hello everyone.
I'm using Miktex, which is supposed to automatically download packages, and WinShell as a front end, both are latest versions.
For some reason packages are not downloading. First the wrapfig.sty file didn't download, so I did it manually by downloading it into the .tex file I'm...
I have no clue how to use it. Can someone tell me in a basic way? Also provide links for downloading?
Note, I haven't even downloaded it. I recently downloaded MikeTex but have no idea how to start this all out. I need this for writing a research paper.
Hello, forum looks like it has good help and I'm certainly in need of that :S
I'm currently working on some pretty basic physics / mechanics stuff, newtonian stuff (up to lorentz transforms)
Re the formatting of this place - I was wondering if an appropriate way to ask a question would be to ...
So, I got the following problem: I want to write my equation the way you can see it in the picture:
I am actually running this:

\begin{split}

\ end{split}
\ end{align}
My problem is, that I can not set multiple align points. I need one point to attach the first 4 lines...

Hello everyone!
I was wondering if you guys could suggest some macro-s that you use in your LaTeX preamble, to speed up typing up your homeworks/reports.
I think typesetting any report looks very professional, so I don't want to stop LaTeX-ing them. However, it does take a huge chunk of my day...
Hello! I am trying to write my notes in mathematics to permanently store my knowledge, and I am trying to learn LaTeX but it is quite difficult for me....Could you recommend me some sources and books to learn LaTeX for mathematics?
Hi people,
I'm having a very hard time to sort the references sequentially in my latex document. Right now my text is displayed as "blabla... [13] blabla.... blabla.... [6]" , so that I get [13] and [6] instead of [1] and [2].
I use bibtex and here's a simplification of the format I use...
I've just noticed that, since I last used it (two weeks ago), Latex has started rendering alphabetic characters in formulas as non-italic, which is non-standard, and doesn't look as good.
See for example my post in this thread.

Problem:
After more than half of my thesis I was advised to use Latex. At this moment I'm learning it, so far looks doable.
However, there is a problem of bibliography... yes, mostly manually formatted as it is supposed to look like in output file... I'd like to use Bibtex... but wouldn't it...

1. As a substitute for a calculator (TI89): making basic graphs, regressions (linear, exponential), vectors, solving equations, showing graphs in 2d and 3d?
2. Writing an ebook with lot's of math.
I'm thinking Mathml or Mathtype might be...
I believe I know the answer to this question; I need an expert to verify it for me.
I work for a company that makes latex balloons. The people that have been here for a long time insist that if one is putting a small (5" balloon) filled with helium inside a larger (30") balloon then one must...
