The polar equation is $\"\"$

Write the equation in standard form: $\"\"$ .

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 hyperbola.

Now $\"\"$ .

Therefore, $\"\"$ .

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

$\"\"$

The eccentricity is $\"\"$ .

The conic is hyperbola.

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