Examples
<math>\sqrt[3]{a x + x^2}</math> produces ![\sqrt[3]{a x + x^2}](/images/math/a/4/8/a480ac1350e2a7645375ceef69ddc69c.png)
The acceleration of a solar sail due to solar pressure 
given the position vector from the sun to the sail 
is:
where 
is max sail acceleration at Earth's distance from the sun (1 AU), 
is the length of an astronomical unit, 
is the magnitude of , and 
is the unit vector normal to the sail surface.
Mimetex
Deprecated. Please follow LaTeX instructions from now on.
Mathematics can be displayed on SolarSailWiki using the Mimetex program, which uses a subset of the LaTeX math formulas. All you need to do is enclose a valid TeX/LaTeX formula inside <tex>...</tex> tags. Formulas will be rendered as GIF images.
