Final answer:
The exact value of arcsin(1/2) is π/4. Hence the correct answer is option B
Step-by-step explanation:
The given question asks to find the exact value of arcsin(1/2). The arcsin function is the inverse of the sin function and represents the angle whose sine is a given value.
To find the exact value of arcsin(1/2), we need to find the angle whose sine is 1/2.
The angle whose sine is 1/2 is π/6 or 30 degrees. Therefore, the correct answer is option (b) π/4.
