Hello, can you help me solve the second subpart of the problem? Thank you!

 

According to Kepler's first law, a comet should have an elliptic, parabolic, or hyperbolic orbit (with gravitational attractions
from the planets ignored). In suitable polar coordinates, the position (r, 9) of a comet satisfies an equation of the form
= ß+e(r• cos 9), where ß is a constant and e is the eccentricity of the orbit, with 0≤e < 1 for an ellipse, e = 1 for
a parabola, and e> 1 for a hyperbola. Suppose observations of a newly discovered comet provide the data below.
Determine the type of orbit, and predict where the comet will be when 9 = 4.1 (radians).
