-0.5
SQRT(3)/4 - 1/4
It is: sin(62) = 0.8829475929.
It is:- sin(40) = 0.6427876097
Sin -30
The second quadrant.
The sine of 210 degrees is equal to -1/2. This value can be derived from the unit circle, where 210 degrees is in the third quadrant, where sine values are negative. Specifically, sin(210°) corresponds to sin(210° - 180°) = sin(30°), and since sine is negative in the third quadrant, sin(210°) = -sin(30°) = -1/2.
