The polar equation is $\"\"$ .

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

The function represents a Limaçon without inner loop.

The polar equation is a function of the cosine function and the period of $\"\"$ is $\"\"$ .

Compute $\"\"$ for different values of $\"\"$ on $\"\"$ .

Plot the points of $\"\"$ and sketch the Limaçon.

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