tan(θ)sin(θ)=3sin(θ)

tan (θ) sin (θ) = 3 sin (θ)

θ = 2 πn, θ = π + 2 πn, θ = 1.24904 \dots + πn

Solution steps

tan (θ) sin (θ) = 3 sin (θ)

Subtract

3 sin (θ)

from both sides

tan (θ) sin (θ) - 3 sin (θ) = 0

Factor

tan (θ) sin (θ) - 3 sin (θ) : sin (θ) (tan (θ) - 3)

sin (θ) (tan (θ) - 3) = 0

Solving each part separately

sin (θ) = 0 or tan (θ) - 3 = 0

sin (θ) = 0 : θ = 2 πn, θ = π + 2 πn

tan (θ) - 3 = 0 : θ = arctan (3) + πn

Combine all the solutions

θ = 2 πn, θ = π + 2 πn, θ = arctan (3) + πn

Show solutions in decimal form

θ = 2 πn, θ = π + 2 πn, θ = 1.24904 \dots + πn

sin (2 x) = 1 - sin (2 x)

3 tan (c) + 8 = 0

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

tan (x) = \frac{14.9}{13.3}

3 sin^{2} (x) + sin (x) - 4 = 0, 0 \leq x \leq 2 π
