WebFeb 11, 2016 · sin(θ) = 1 √2 = √2 2 or sin(θ) = − 1 √2 = − √2 2. θ = π 4 +2kπ or θ = 3 π 4 + 2kπ or. θ = 5 π 4 + 2kπ or θ = 7 π 4 + 2kπ. If you trace these four solutions in the trigonometrical circle you will see that the four can be resumed in just one: θ = π 4 + kπ 2. Answer link. WebApr 7, 2024 · So, either tan(θ) + tan(2θ) = 0, or tan(θ) = 0, or tan(2θ) = 0. tan(θ) + tan(2θ) = 0 tan(θ) + 2tan(θ) 1 − tan2(θ) = 0 3tan(θ) − tan3(θ) = 0 tan(θ) ∈ {0, ± √3} So θ ∈ {nπ, ± 1 3π + nπ, ± 1 4π + nπ: n ∈ Z} Share.
