Sin(2 radians) = approx 0.9093
1.11842 sine 34°= 2 * sine 34°= 2 * 0.55919= 1.1184
Sine of 225 degrees = - 0.5 sqrt(2)
√ 1/2 = sine(45)= cosine(45) -Key
Sine(120) = sqrt(3/4) or sqrt(3)/2 = 0.866025
sqrt 2 / 2 is the answer.
Divide -900 by 360, and the remainder will be the angle you need to find the sine of: -900 / 360 = -2.5 --> -900 = 360*(-2 - 0.5), so sine(-180°) = sine(-900°). sine(-180°) = 0
(sqrt 2) / 2
cosecant of C + cosecant of D = -2 sine of (C+D)/2 X sine of (C - D)/2
sin60° = √3/2
