The polar equation is
.
\
The polar equation is
.
Rewrite the equation as : 

Compare the equation with
.
p = distance between the pole and the directix = 4.
\
and pole = (0, 0). \ \
So, the graph represents an ellipse.
\So, the graph of the conic is at vertical directix above the pole.
\The polar function is
.
Make the table of values to find ordered pairs that satisfy the function.
\Choose random values for
and find the corresponding values for r.
