Evaluate 2sin(pi)

Problem

2*sin(π)

Solution

1. Identify the value of the trigonometric function sin(π)

2. Recall that on the unit circle, the sine of an angle corresponds to the ycoordinate of the point at that angle.

3. Determine that at π radians (180, the coordinates are (−1,0) so sin(π)=0

4. Substitute the value back into the original expression: 2*(0)

5. Multiply the constants to find the final result.

Final Answer

2*sin(π)=0
