# A few LaTeX tricks

I learned several neat LaTeX tricks in the past few days. The first is how to write LaTeX in my wordpress blog entry:

$e^{\i \pi} + 1 = 0$ or $e^{\i \pi} + 1 = 0$ syntax.

To write it, you enclose the mathtype you want like: [tag] e^{\i \pi} + 1 = 0 [/tag] (but replace tag with the word: latex).

$e^{\i \pi} + 1 = 0$ or $e^{\i \pi} + 1 = 0$ syntax.
Using the plugin: WP LaTeX

The second trick came from trying to set my paper in twocolumn mode and getting the figures to plot correctly. I used to scale by hand, when I was told that you can set the width using a multiple of textwidth (in the following example, one half of the textwidth):

\includegraphics[angle=-90,width=0.5\textwidth]{figvshiftu.eps}

The third and final thing I learned was that while adding a * to equations will keep them from being numbered, if you add it to figure, it breaks out of double column mode for that figure only.

\begin{figure*} \end{figure*}

It even works (for emulateapj) with deluxetables.
