2016-03-08 · This result follows almost directly from the following: (a+b)^2 = a^2+2ab + b^2 sin^2(x) + cos^2(x) = 1 sin(2x) = 2sin(x)cos(x) With these, we have (sin(x)+cos(x))^2 To find the value of sin2x × Cos 2x, the trigonometric double angle formulas are used. For the derivation, the values of sin 2x and cos 2x are used. From trigonometric double angle formulas, Sin 2x = 2 sin x cos x ———— (i) Have you ever been told that sine squared plus cosine squared equals one? Did your teacher explain why that's true?
