If sin A = 1/2, what is the value of A in radians?

If sin A = 1/2, what is the value of A in radians?

Step 1: Understand that sin A = 1/2 means we are looking for an angle A where the sine value is 1/2.
Step 2: Recall the unit circle and the common angles. The sine of an angle is the y-coordinate of the point on the unit circle.
Step 3: Identify the angle where the sine value is 1/2. This occurs at π/6 radians (or 30 degrees).
Step 4: Confirm that there are other angles where sin A = 1/2, but the question asks for the value of A in radians, so we focus on the principal value.
Step 5: Conclude that the value of A is π/6 radians.
