Statement: sin ⁡ ( 2 x) = 2 sin ⁡ ( x) cos ⁡ ( x) Proof: The Angle Addition Formula for sine can be used: sin ⁡ ( 2 x) = sin ⁡ ( x + x) = sin ⁡ ( x) cos ⁡ ( x) + cos ⁡ ( x) sin ⁡ ( x) = 2 sin ⁡ ( x) cos ⁡ … Sin 2x Cos 2x is one such trigonometric identity that is important to solve a variety of trigonometry questions.

You have seen quite a few trigonometric identities in the past few pages. It is convenient to have a summary of them for reference. These identities mostly refer to one angle denoted θ, but there are some that involve two angles, and for those, the two angles are denoted α and β.: The more important identities.
