Question: 1. Give inequalities that describe the flat surface of a washer that is one inch in diameter and has an inner hole with a diameter of 3/8 inch.
2. Graph the equation r = 1 - sin(2θ) for 0 ≤ θ ≤ 2π. There are two loops. For each loop, give a restriction on θ that shows all of that loop and none of the other loop.
