2|sin(4θ)|=0

2 ∣ sin (4 θ) ∣ = 0

θ = \frac{πn}{2}, θ = \frac{π}{4} + \frac{πn}{2}

Solution steps

2 ∣ sin (4 θ) ∣ = 0

Divide both sides by

2

∣ sin (4 θ) ∣ = 0

Apply absolute rule: If

∣ u ∣ = 0

then

u = 0

sin (4 θ) = 0

General solutions for

sin (4 θ) = 0

4 θ = 0 + 2 πn, 4 θ = π + 2 πn

Solve

4 θ = 0 + 2 πn : θ = \frac{πn}{2}

Solve

4 θ = π + 2 πn : θ = \frac{π}{4} + \frac{πn}{2}

θ = \frac{πn}{2}, θ = \frac{π}{4} + \frac{πn}{2}

250 sin (7 5^{\circ}) = 393.19 sin (4 5^{\circ} - θ)

tan (θ) = \frac{6}{6.71}

x, sin (x) - 1 = 0

sin^{2} (θ) = 1 + cos (2 θ)

4 sin^{2} (θ) = 3 - 2 sin^{2} (θ)
