I cant understand what the question is asking~ hope somebody can help me~(adsbygoogle = window.adsbygoogle || []).push({});

A particle of mass m moves in a plane under the influence of Newtonian gravitation force, described by the potential V(r) = - GmM/r (symbol in conventional meaning)

Now introduce a new variable u(theta) = 1/r(theta) and obtain an equation satisfied by u. Find the equation of the orbit in polar coordinates. What are the allowed trajectories of the particle?
