Answer:


(\pi)/(4),(3\pi)/(4)

Explanation:


2\sin^2(\theta)=1

Divide both sides by 2:


\sin^2(\theta)=(1)/(2)

Take the square root of both sides:


\sin(\theta)=(1)/(√(2))=(√(2))/(2)

The only two places on the unit circle where the y value of the point is
(√(2))/(2) are at:


(\pi)/(4),(3\pi)/(4)

Hope this helps!
