Explanation Suppose that sinx cosx Rsin x alpha Then sinx cosx Rsinxcosalpha Rcosxsinalpha Rcosalpha sinx Rsinalpha cosx The coefficients of sinx and of cosx must be equal so Squaring and adding we get R 2cos 2alpha R 2sin 2alpha 2 so R 2 cos 2alpha sin 2alpha 2 R sqrt2 cos x sin x sin 2x 2 So we have cos x sin x If we multiply it by two we have 2cos x sin x Which we can say it s a sum cos x sin x sin x cos x Which is the double angle formula of the sine cos x sin x sin x cos x sin 2x But since we multiplied by 2 early on to get to that we need to divide by two to make the equality
