### 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}.
\begin{equation} % arbitrary environments,
x=\sqrt{b} % even tables, figures
\end{equation} % etc
If $a^2=b$ and \( b=2 \), then the solution must be
either $$ a=+\sqrt{2} $$ or \[ a=-\sqrt{2} \].
