cos ⁡ 2 X = cos ⁡ ( X + X) = cos ⁡ X cos ⁡ X – sin ⁡ X sin ⁡ X. \cos 2X = \cos \left ( X+X \right ) = \cos X \cos X – \sin X \sin X cos2X = cos (X + X) = cosX cosX – sinX sin X. cos ⁡ 2 X = cos ⁡ 2 X – sin ⁡ 2 X. Statement: $$\sin(2x) = 2\sin(x)\cos(x)$$ Proof: The Angle Addition Formula for sine can be used: $$\sin(2x) = \sin(x + x) = \sin(x)\cos(x) + \cos(x)\sin(x) = 2\sin(x I tried: $(\sin^2(x))^2 = ((1-\cos2x)/2)^2$ but still getting $\cos x$ to the power of $2$. Wolframalpha only shows the answer which i have no idea how they got it. Could somebody help ? 2008-11-06 · sin 2x = 2 tan x / (1 + tan^2 x)-----Expand out cos 2x using the double angle formula as 2 cos^2 x - 1.
