R=5sin2θ
Web5sin2θ = 10sinθcosθ = 9tanθ = 9sinθ/cosθ. One solution is sinθ = 0, which gives θ = 0 in the specified range. Dividing by sinθ we get 10cosθ = 9/cosθ. Hence (cosθ)^2 = 9/10 and. cosθ = ±3/√10. This provides solutions ±18.4, ±161.6. Hence the complete solution set is θ = -161.6, - 18.4, 0, 18.4 and 162.6. More answers below ...
