To determine

To sketch:The region whose coordinates are given

Answer to Problem 12E

  

Explanation of Solution

Given: $r\ge 1,$

  $\pi \le \theta \le 2\pi$

Calculation:

This region is all of the points between the angles $\pi$ and $2\pi$ , with any radius greater than 1:

  

Conclusion:

Therefore, theregion is drawn whose coordinates satisfies the given conditions
