Question 53

Given that sin⁡θ+cos⁡θcot⁡θ≡csc⁡θ\sin \theta + \cos \theta \cot \theta \equiv \csc \thetasinθ+cosθcotθ≡cscθ,

Hence find the exact roots of the equation sin⁡θ+cos⁡θcot⁡θ=4sin⁡θ\sin \theta + \cos \theta \cot \theta = 4 \sin \thetasinθ+cosθcotθ=4sinθ, for 0≤θ≤2π0 \leq \theta \leq 2\pi0≤θ≤2π
