### 11.3 Embedded LaTeX

For scientific notes which need to be able to contain mathematical symbols and the occasional formula, Org mode supports embedding LaTeX code into its files. You can directly use TeX-like syntax for special symbols, enter formulas and entire LaTeX environments.

The radius of the sun is R_sun = 6.96 x 10^8 m.  On the other hand,
the radius of Alpha Centauri is R_{Alpha Centauri} = 1.28 x R_{sun}.

$$% arbitrary environments, x=\sqrt{b} % even tables, figures$$                          % etc

If $a^2=b$ and $$b=2$$, then the solution must be
either $$a=+\sqrt{2}$$ or $a=-\sqrt{2}$.
