Question

HELP PLS it’s really urgent

Answer 1

Option (4)

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.
