Chapter H.1, Problem 11E

To determine

To sketch: The region whose coordinates are given

Answer to Problem 11E

  

Explanation of Solution

Given:

  $2<r\le 3,$

  $\frac{5\pi }{3}\le \theta \le \frac{7\pi }{3}$

Calculation:

This region is all of the points between the angles $\frac{3\pi }{4}$ and $\frac{5\pi }{4}$ , with any radius between 2 and 3:

  

Conclusion:

Therefore, theregion is drawn whose coordinates satisfies the given conditions
