Question

Identify the conic that the polar equation represents.Also,give the position of the directrix.

Answer 1

Step 1:

The polar equation is .

Compare this polar equation with .

Directrix is perpendicular to the polar axis at a distance units to the right of the pole.

.

Here , so the conic is a parabola.

Then the directrix is perpendicular to the polar axis at a distance 1 unit to the right of the pole.

Solution :

The conic is a parabola.

Directrix is perpendicular to the polar axis 1 unit to the right of the pole.
