Example short equation:

: <math> E = mc^2 </math>

renders like this:

E=mc^{2}

Here's Ferguson & Church (2004^[1]) version of the Stokes equation:

:<math>w = \frac{R g D^2}{C_1 \nu + \sqrt{0.75\,C_2\, R g D^3}}</math>

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

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.
