sine 10. Use the cofunction with the complementary angle.
sec x - cos x = (sin x)(tan x) 1/cos x - cos x = Cofunction Identity, sec x = 1/cos x. (1-cos^2 x)/cos x = Subtract the fractions. (sin^2 x)/cos x = Pythagorean Identity, 1-cos^2 x = sin^2 x. sin x (sin x)/(cos x) = Factor out sin x. (sin x)(tan x) = (sin x)(tan x) Cofunction Identity, (sin x)/(cos x) = tan x.
all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
The sine of 57 degrees is approximately 0.8387.
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
If sin(theta) is 0.9, then theta is about 64 degrees or about 116 degrees.
sin(90) = 1
It is:- sin(40) = 0.6427876097
