### Examples

$\sqrt[3]{a x + x^2}$ 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.
