Sin 12 in terms of cosine

WebbWe know, from the basic definitions of sine and cosine, that sin is opposite/hypotenuse, and cos is adjacent/hypotenuse. So no, what you stated is wrong. Second, I am not really sure how you arrived at that conclusion, but from what I infer, you assumed that the square root was separate for the one and the sinA.
