-3sin(θ)=0

- 3 sin (θ) = 0

θ = 2 πn, θ = π + 2 πn

Degrees

θ = 0^{\circ} + 36 0^{\circ} n, θ = 18 0^{\circ} + 36 0^{\circ} n

Solution steps

- 3 sin (θ) = 0

Divide both sides by

- 3

- 3 sin (θ) = 0

Divide both sides by

- 3

\frac{- 3 sin ( θ )}{- 3} = \frac{0}{- 3}

Simplify

sin (θ) = 0

sin (θ) = 0

θ = 0 + 2 πn, θ = π + 2 πn

θ = 0 + 2 πn, θ = π + 2 πn

Solve

θ = 0 + 2 πn : θ = 2 πn

θ = 0 + 2 πn

0 + 2 πn = 2 πn

θ = 2 πn

θ = 2 πn, θ = π + 2 πn

\frac{cos ( x )}{sin ( x )} = 1

- 2 tan (θ) - 4 - tan^{2} (θ) = - 3

cos^{2} (x) = 3 - 5 cos (x)

sin (x) = \frac{1}{sec ( x )}

x, 1 - 2 cos^{2} (x) - 2 cos (x) = 0
