"WebYou can think of sin (θ) as cos (90°-θ). This is because, as doctorfoxphd said, the sine of one angle is the cosine of its compliment. That's actually why it's called co-sine, because it's the sine of the complimentary angle. This is also the relationship between all the other cofunctions in trigonometry: tan (θ)=cot (90°-θ), sec=csc (90°-θ). " - Right angle sin
