The Eccentricity Is Given of a Conic Section with One e=14,x=2e = \frac { 1 } { 4 } , x = 2

Question 345

Multiple Choice

The eccentricity is given of a conic section with one focus at the origin, along with the directrix corresponding to that focus. Find a polar equation for the conic section.
- e=14,x=2e = \frac { 1 } { 4 } , x = 2


A) r=24+cosθr = \frac { 2 } { 4 + \cos \theta }
B) r=24+sinθr = \frac { 2 } { 4 + \sin \theta }
C) r=21+4cosθr = \frac { 2 } { 1 + 4 \cos \theta }
D) r=24cosθr = \frac { 2 } { 4 - \cos \theta }
