Clever ideas in LaTeX
This thread is your chance to show off clever things you've found you can do in LaTeX so that they inspire others to learn more about LaTeX.

I'll start it off with a couple of things that I've already posted in another thread:
\setlength{\unitlength}{0.5cm}\begin{picture}(5,2) \put(5,0){\line(-1,0){5}}\put(0,0){\line(1,1){2}}\put(2,2){\line(3,-2){3}}... and \setlength{\unitlength}{2mm}\begin{picture}(30, 20) \linethickness{0.075mm}\multiput(0, 0)(1, 0){31}{\line(0, 1){20}}\multipu...

OK, over to you. Even if you've already posted something good elsewhere then do repeat it here (hint to i_like_pie Smile)

Re: Clever ideas in LaTeX
Code:
$\setlength{\unitlength}{0.5cm}\begin{picture}(5,2) \put(5,0){\line(-1,0){5}}\put(0,0){\line(1,1){2}}\put(2,2){\line(3,-2){3}}\put(-0.5,-0.1){\small A}\put(1.9,2.1){\small B}\put(5.1,-0.1){\small C}\put(4,0.1){\tiny 30}\qbezier(3.8,0)(3.9,0.55)(4.1,0.55) \put(0.6,1){\footnotesize 2}\put(3.6,1){\footnotesize 3}\put(2.3,-0.6){\footnotesize 5}\put(-1,-0.2){\tiny \shortstack{i\\m\\p\\o\\s\\s\\i\\b\\l\\e}}\put(6,-0.2){\tiny \shortstack{t\\r\\i\\a\\n\\g\\l\\e}}\end{picture}$ and $\setlength{\unitlength}{2mm}\begin{picture}(30, 20) \linethickness{0.075mm}\multiput(0, 0)(1, 0){31}{\line(0, 1){20}}\multiput(0, 0)(0, 1){21}{\line(1, 0){30}}\linethickness{0.15mm}\multiput(0, 0)(5, 0){7}{\line(0, 1){20}}\multiput(0, 0)(0, 5){5}{\line(1, 0){30}}\linethickness{0.3mm}\multiput(5, 0)(10, 0){3}{\line(0, 1){20}}\multiput(0, 5)(0, 10){2}{\line(1, 0){30}}\end{picture}$

So people can see what you wrote...

Yes, if you think it will be helpful to others and perhaps inspire them.

Note that if you hold the cursor over a \LaTeX image, the source code will be displayed in a box. I realize that this is not quite as easy to read, but it is something to keep in mind.

I noticed that, too, but it only displays the first line or so.

To get the entire code, you can do one of two things:

1. Quote the post and copy the code.
2. If the topic is locked (you can't quote anymore), right-click the image and click Properties. The code is in Miscellaneous Properties.

Doesn't it take a looooong time to type that all up...

Isn' it faster to do with Geometer's sketchpad? Huh?

Eww, geometer's sketchpad is so ugly. Besides you can't even export it to TeX or ps.

If you're going to use a geometry program to do that stuff try Kig (http://edu.kde.org/kig/) I think with enough work you can make KDE and thus kig run under Windows.

Anyone know how to \renewcommand{\today} so that you can get a date like 21.12.2006?

Edit: \renewcommand{\today}{\number\day.\number\month.\number\year}

I do hope that we'll soon have available on the server Asymptote.

Here is a Table of Variations -- uses the package "tableau" by N. Kisselhoff (http://melusine.eu.org/syracuse/exemples/tarass/tableau/). Under CTAN its name is "tableaux"

The package is a PSTricks implementation of the vast array of packages written to draw these tables. Unfortunately the documentation is written in French, and to learn this package I had to spend most of my Saturday translating it back to English using Google Translate Blush Blush Blush I hope to submit an English doc within this year -- I think so far this is the best package to draw these tables without having to resort to MetaPost (for somebody who has no more time to learn a new language!)
