Question

Quizplus · Accepted Answer

For a polar equation of the form $ r = \frac { l } { 1 + e \cos \theta } $, the conic section is determined by the eccentricity $ e $. If $ e > 1 $, the conic is a hyperbola. Since $ e = 1.8 $ is greater than 1, the conic is a hyperbola.

Identify the conic for the polar equation r=2e1+ecos⁡θ when e=1.8. \text { Identify the conic for the polar equation } r = \frac { 2 e } { 1 + e \cos \theta } \text { when } e = 1.8 \text {. } Identify the conic for the polar equation r=1+ecosθ2e​ when e=1.8.
