Question

HELP PLS it’s really urgent

Answer 1

Answer:

Option (4)

Step-by-step explanation:

Given expression is,

$\sqrt{1-\text{cos}^2\theta}=-\text{sin}\theta$

Since, $\sqrt{1-\text{cos}^2\theta}=\pm \text{sin}\theta$

If $\sqrt{1-\text{cos}^2\theta}=-\text{sin}\theta$

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.
