Find the Value Using the Unit Circle sin(30)

Problem

sin(30)

Solution

1. Identify the angle on the unit circle. The angle is 30 which is equivalent to π/6 radians.

2. Locate the coordinates (x,y) for 30 on the unit circle. At this position, the coordinates are (√(,3)/2,1/2)

3. Apply the definition of the sine function on the unit circle. The value of sin(θ) corresponds to the ycoordinate of the point.

4. Extract the ycoordinate from the point (√(,3)/2,1/2)

Final Answer

sin(30)=1/2
