1. The problem statement, all variables and given/known data sin 2θ = sin θ Find the solutions in degrees. 2. Relevant equations sin 2θ = 2sinθcosθ 3. The attempt at a solution sin 2θ = sin θ 2sinθcosθ = sin θ sinθ *cosθ/sin θ = 1 That's as far as I can get, and I think that is wrong. How do I procede from 2sinθcosθ = sin θ?
