Answer:
Option (4)
Step-by-step explanation:
Given expression is,
[tex]\sqrt{1-\text{cos}^2\theta}=-\text{sin}\theta[/tex]
Since, [tex]\sqrt{1-\text{cos}^2\theta}=\pm \text{sin}\theta[/tex]
If [tex]\sqrt{1-\text{cos}^2\theta}=-\text{sin}\theta[/tex]
And sine of angle θ is negative in quadrants III and IV.
Therefore, angle θ will terminate in quadrants III and IV.
Therefore, Option (4) will be the correct option.
