Help:Mathematics

• Math is handled by the LaTeX typesetting system
• Don’t use equation numbers
• Indent block equations with a colon (see examples below)
• The Mediawiki software 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: $E=mc^{2}$

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

$E=mc^{2}\$

Longer equations render as images regardless; here's Ferguson & Church (2004) version of the Stokes equation:

$w={\frac {RgD^{2}}{C_{1}\nu +{\sqrt {0.75\,C_{2}\,RgD^{3}}}}}$

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.
