Step 1:
\The polar equation
.
To identify the type of conic, rewrite the equation in the form
is a conic,
where
is the eccentricity and
is the distance between the focus(pole) and the directrix.

Divide numarator and denominator by 2.
\

Compare with
.

Since
, the equation is ellipse.
Graph the above polar equation using some polar coordinates.
