Question

indicate the two quadrants θ could terminate in if sin θ = 3/√18 quadrants or

Explanation:

Step1: Recall sine - value sign in quadrants

The sine function $y = \sin\theta=\frac{y}{r}$, where $r=\sqrt{x^{2}+y^{2}}>0$. $\sin\theta$ is positive when $y>0$.

Step2: Identify positive - sine quadrants

In the unit - circle, $\sin\theta>0$ in the first and second quadrants.
