Solve 2 sin x = 1 for x in the interval 0 to pi/2.

Answer and explanation

Correct answer: A. pi/6

  1. Step 1: Divide by 2: sin x = 1/2. Step 2. In the interval 0 to pi/2 the angle is pi/6. Answer: pi/6. Why not the others: pi/3: That gives sin x = root 3/2. pi/4: That gives sin x = root 2/2. pi/2: That gives sin x = 1.
