Double Angle Identities | Brilliant Math & Science Wiki Use the double angle formulas to prove the identity \csc 2\theta - \cot 2\theta = \tan \theta. csc2θ−cot2θ = tanθ. We have \begin {aligned} \csc 2\theta - \cot 2\theta &= \dfrac {1} {\sin 2\theta} - \dfrac {\cos 2\theta} {\sin 2\theta} \\ \\ &= \dfrac {1-\cos 2\theta} {\sin 2\theta}. \end {aligned} csc2θ −cot2θ = sin2θ1 − sin2θcos2θ = sin2θ1−cos2θ.

Front page - Mechamath Proof of the double angle identities. The double angle identities are derived using the angle sum identities. In the case of the sum of angles in a sine, we have: sin ( α + β) = sin ( α) cos ( β) + cos ( α) sin ( β) If α and β were the same angle, we would have: sin ( α + α) = sin ( α) cos ( α) + cos ( α) sin ( α)
