Cos Sin 1 X 2

sin(2x) = 2 sin x cos x cos(2x) = cos ^2 (x) - sin ^2 (x) = 2 cos ^2 (x) - 1 = 1 - 2 sin ^2 (x) tan(2x) = 2 tan(x) / (1 - tan ^2 (x)) sin ^2 (x) = 1/2 - 1/2 cos(2x) cos ^2 (x) = 1/2 + 1/2. When we divide Sine by Cosine we get: sin (θ) cos (θ) = Opposite/Hypotenuse Adjacent/Hypotenuse = Opposite Adjacent = tan (θ) So we can say: tan (θ) = sin (θ) cos.
