The polar equation is $\"\"$ .

The standard form of polar rquation is $\"\"$ .

Where $\"\"$ is the eccentricity and $\"\"$ represents the line of directrix.

$\"\"$

$\"\"$ .

Compare the above equation with the standard form of polar equation.

Here $\"\"$ and $\"\"$ .

Since the eccentricity is $\"\"$ , the conic represents a ellipse.

Consider $\"\"$ .

Substitute $\"\"$ .

$\"\"$

$\"\"$ .

The equation of directrix is $\"\"$ .

$\"\"$

The eccentricity is $\"\"$ .

The conic is ellipse.

The equation of directrix is $\"\"$ .
