Step 1: the polar equation $\"\"$ .

Symmetry with respect to the line $\"\"$ .

Maximum value of $\"\"$ : $\"\"$ when $\"\"$ .

Zeros of $\"\"$ : $\"\"$ when $\"\"$ .

Construct a table for a different values of $\"\"$ .

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

$\"\"$	$\"\"$	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \
\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \	\ $\"\"$ \

Step 2:

Graph:

Draw the polar coordinate plane.

$\"\"$

Plot the polar coordinates.

Connect the points with smooth curve.

$\"\"$ .

Solution:

$\"\"$ .
