Help:Math

LaTeX

You can enter LaTeX equations by enclosing them in <math>...</math> tags. This uses the Math extension. For LaTeX math help, see:

• LaTeX documentation
  • The Not so Short Introduction to LaTex - with a very complete chapter on typesetting mathematical formulas

Examples

<math>\sqrt[3]{a x + x^2}</math> produces $\sqrt[3]{a x + x^2}$

The acceleration of a solar sail due to solar pressure $\vec a_s$ given the position vector from the sun to the sail $\vec r_s$ is:

$\vec a_s = a_c {AU^2 \over r_s^2} \left(\vec r_s \cdot \vec n\right)^2 \vec n$

where $a_c$ is max sail acceleration at Earth's distance from the sun (1 AU), $AU$ is the length of an astronomical unit, $r_s$ is the magnitude of $\vec r_s$, and $\vec n$ 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.
