How To Solve Double Angle Identities, Begin with the compound angle formula: sin(α + β) = sin(α)cos(β) + sin( . Because we do not know \begin{align*}\cos x\end{  Double angles can be expressed using trigonometric functions such as sine, cosine, and tangent. Solution: Using the double angle formula, \begin{align*}\sin 2x = 2 \sin x \cos x\end{align*}.
