Conic Sections in Polar Coordinates
1 Define Conics in Terms of a Focus and a Directrix
- $$r = \frac { 5 } { 4 + 2 \cos \theta }$$

A) ellipse; The directrix is $\frac { 5 } { 2 }$ unit(s) to the right of the pole at $x = \frac { 5 } { 2 }$ .
B) ellipse; The directrix is $\frac { 5 } { 2 }$ unit(s) to the left of the pole at $x = - \frac { 5 } { 2 }$ .
C) ellipse; The directrix is $\frac { 5 } { 2 }$ unit(s) below the pole at $y = - \frac { 5 } { 2 }$ .
D) ellipse; The directrix is $\frac { 5 } { 2 }$ unit(s) above the pole at $y = \frac { 5 } { 2 }$ .
