- Math is handled by the LaTeX typesetting system
- Don’t use equation numbers
- Indent block equations with a colon (see examples below)
- Mediawiki will render HTML characters for short equations, and PNG images for longer ones
- To force image rendering, add a space at the end of the equation with a solidus (backslash) followed by a space

## Examples

Example short equation:

Example short equation with forced image rendering, using a space at the end of the equation:

Longer equations render as images regardless; here's the Aki-Richards equation:

## Style

- Constants and names or label are roman (i.e. upright, not italic):
*V*_{P}. Use**\mathrm{P}**in LaTeX math. - Pi, e, the differential d, and lots of other symbols are usually roman
- Variables are italic (the default character style in LaTeX math)
- Vectors are roman and bold (use
**\mathbf{}**— it's best to avoid**\vec{}**, which uses the arrow notation) - Use the built-in LaTeX functions for
**\sin**,**\log**, etc.
