Problem

Answer the following. (1) Use the identity cos⁡2θ+sin⁡2θ=1\cos^2\theta + \sin^2\theta = 1 to prove that tan⁡2θ=sec⁡2θ−1\tan^2\theta = \sec^2\theta - 1. (2) Solve, for 0≤θ≤3600 \leq \theta \leq 360, the equation tan⁡2θ+sec⁡2θ+5sec⁡θ=2\tan^2\theta + \sec^2\theta + 5\sec\theta = 2 Give your answers to 1 decimal place.
