Find the Exact Value 2sin(pi)

Problem

2*sin(π)

Solution

1. Identify the angle π on the unit circle.

2. Recall the coordinates of the point on the unit circle at an angle of π radians are (−1,0)

3. Determine the value of sin(π) by looking at the ycoordinate of that point.

sin(π)=0

4. Substitute the value of sin(π) back into the original expression.

2*(0)=0

Final Answer

2*sin(π)=0
