Deriving sin and cos
Webcos2 + sin2 = 1 Other trignometric identities re ect a much less obvious property of the cosine and sine functions, their behavior under addition of angles. This is given by the … Websin A = (side opposite to A) / (long side) cos A = (side adjacent to A) / (long side) Because the side opposite to A is the one adjacent to (90°– A), it follows that the sine of one angle is the cosine of the other, and vice versa: sin A = a …
