The eccentricity is $\"\"$ and directrix is $\"\"$ .

The directrix is horizontal and above the pole, then the polar equation of the conic

is $\"\"$ .

The distance between the pole and directrix is $\"\"$ .

Substitute $\"\"$ and $\"\"$ in the polar equation $\"\"$ .

$\"\"$

The polar equation of the conic is $\"\"$ .
