Observe the garph :

The graph is a circle centered at the origin with radius $\"\"$ , or the set of all points that are

$\"\"$ from the pole.

This set of the points take on the form $\"\"$ , where $\"\"$ is any angle measure.

Two equations that match this description is $\"\"$ and $\"\"$ .

The graph is a circle cuts the origin at $\"\"$ and $\"\"$ .

The equations are $\"\"$ and $\"\"$ .
