This site is here to facilitate mathematical and computational discussion. As such, it is often nice to format your questions and responses as nicely as possible - including typeset mathematics, images, and code as appropriate.
Sections and other formatting
Textual entry into discourse is based on Markdown - a lightweight markup language that makes formatting relatively easy. To start this particular section, for example, I simply entered:
## Sections and other formatting
Creating a bulleted list is as easy as indenting with asterisks. To get this:
- First item
- Second item
- A sub item
Just type this:
* First item
* Second item
* A sub item
And code like the above is entered by indenting four spaces.
To create typeset mathematics, simply enter a LaTeX snippet. For example, to generate this:
If f(x) = e^{-x^2}, then
I simply typed
If $f(x) = e^{-x^2}$, then
$$
\int_{-\infty}^{\infty} f(x) = \sqrt{\pi}.
$$
Note the single dollar signs versus the double dollar signs. Also, the current Math Typesetting plugin is a little odd in how the way it requires the double dollar signs to be on separate lines.
