all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
The sine of 57 degrees is approximately 0.8387.
sin(16) = -0.28790331666507
cos(α) = sin(90° - α) → cos(16° + θ) = sin(90° - (16° + θ)) = sin(74° - θ) → sin(36° + θ) = cos(16° + θ) → sin((36° + θ) = sin(74° - θ) → 36° + θ = 74° - θ → 2θ = 38° → θ = 19° → θ = 19 °+ 180°n for n= 0, 1, 2, ...
Sin theta of 30 degrees is1/2
sin(90) = 1
It is:- sin(40) = 0.6427876097
If sin(theta) is 0.9, then theta is about 64 degrees or about 116 degrees.
SQRT(3)/4 - 1/4
It is:- sin(40) = 0.6427876097
It is: sin(62) = 0.8829475929.
Sin(163 degrees) = 0.2924 approx.
