The polar equation is $\"\"$ .

$\"\"$

$\"\"$ .

Compare the polar equation with standard form of conic equation: $\"\"$ , where $\"\"$ is eccentricity and $\"\"$ is directrix.

Here, $\"\"$ , $\"\"$ .

$\"\"$

$\"\"$ .

The eccentricity and the form of the equation determine that it is a ellipse that opens horizontal line with focus at the pole and directrix $\"\"$ .
