Determine whether the expression is position or negative sin(121 degrees)
To determine whether the expression sin(121 degrees) is positive or negative, we need to consider the angle's position in the unit circle.
In the unit circle, the positive x-axis is at 0 degrees and the positive y-axis is at 90 degrees. As we move in a counterclockwise direction, the values of sine are positive for angles in the first and second quadrants (0 to 180 degrees).
Since 121 degrees is in the second quadrant (between 90 and 180 degrees), we can conclude that sin(121 degrees) is positive.
