More Trig Identities

This section covers longer identity proofs on Paper 2. You still only have the quotient tan⁡θ=sin⁡θcos⁡θ\tan\theta=\dfrac{\sin\theta}{\cos\theta} (where cos⁡θ≠0\cos\theta\neq 0), the square sin⁡2θ+cos⁡2θ=1\sin^2\theta+\cos^2\theta=1, and 1+tan⁡2θ=1cos⁡2θ1+\tan^2\theta=\dfrac{1}{\cos^2\theta}. An identity is true for every
