Solve, for 0 < θ < 2π, sin 2θ + cos 2θ + 1 = √6 cos θ , giving your answers in terms of π. Since there is a single power of cos θ I will aim to write as much of the equation in cos θ 2sin θcos θ + 2cos2 θ = √6 cos θ. Factorising gives: Cos θ(2sin θ + 2cos θ - √6) =0. Therefore: cos θ = 0 θ = or 2sin θ + 2cos θ - √6 = 0
