Cos 2 Sin 2 1. This is given by the following two formulas, which are not at all obvious cos( 1 + 2) =cos 1 cos 2 sin 1 sin 2 sin( 1 + 2) =sin 1 cos 2 + cos 1 sin 2 (1) Just as the distance between the origin and any point (x,y) on a circle must be the circle's radius, the sum of the squared values for sinθ and cosθ must be 1 for any angle θ.

Web satisfying x2 + y2 = 1, we have cos2 + sin2 = 1 other trignometric identities re ect a much less obvious property of the cosine and sine functions, their behavior under addition of angles. Web cos2θ +sin2θ = 1 this is often rewritten with the sin2 term in front, like this: Web what is cos(2 sin−1 x)? Web so, cos 2 θ + sin 2 θ = (x/r) 2 + (y/r) 2 = (x 2 +y 2 )/r 2 = r 2 /r 2 = 1 upvote • 1 downvote add comment report ray b.
