WebNov 3, 2024 · You can rewrite the expression on the left side: a ⋅ sin(θ) + b ⋅ cos(θ) = Asin(θ + τ) = A ⋅ sin(θ)cos(τ) + A ⋅ cos(θ)sin(τ) You can express tan(θ + τ) using cos(θ + τ) = + − √1 − sin2(θ + τ). Use the identity arcsin(x) = arctan( x √1 − x2) with x = a c a√a2 + b2 to get. where k1, k2 ∈ Z and a ≠ 0. As desired. WebJun 5, 2024 · 2sin2θ − 2sinθ = 0. 2sinθ(sinθ −1) = 0. sinθ = 0 or sinθ = 1. Because we squared the sign of the cosine is ambiguous from the first clause. But only one sign will work. These are really. sinθ = 0 and cosθ = − 1 or sinθ = 1. We conclude θ = π+ 2πk or θ = π 2 +2πk integer k. Answer link.
