Math … Web12 jul. 2024 · We know that sin(30 ∘) = 1 2 and cos(30 ∘) = √3 2. Since 150 degrees is in the second quadrant, the x coordinate of the point on the circle would be negative, so the cosine value will be negative. The y coordinate is positive, so the sine value will be positive. sin(150 ∘) = 1 2 and cos(150 ∘) = − √3 2

Web14 sep. 2015 · Not in general, no, because cos x = cos ( x + 2 π) but cos ( α x) ≠ cos ( α ( x + 2 π)) when α is not an integer. So if you could write: g ( x) = cos ( α x) = f ( cos x) for some function f, then cos ( α ( x + 2 π)) = g ( x + 2 π) = g ( x) = cos ( α x) for all x. That is only true for α an integer.

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). do paystubs say this is not a check
