$\"\"$

The polar equation is $\"\"$ .

The equation is of the form $\"\"$ and $\"\"$ .

The function represents a Limaçon with inner loop.

Because this polar equation is a function of the cosine function, it is symmetric with respect to the polar axis.

Construct a table and calculate the values of $\"\"$ on $\"\"$ .
