Question

In which quadrant is $\theta$, if $\sin \theta$ is positive and $\cos \theta$ is negative?

• A. I
• B. II
• C. III
• D. IV

Answer 1

Answer: (B)

II

$\sin \theta$ is positive in quadrant I and II. But, $\cos \theta$ is +ve in quadrant I and negative in quadrant II.
Thus, in quadrant II lies $\theta$, because $\sin \theta$ is positive and $\cos \theta$ is negative.
