tan(θ)sin(θ)-4tan(θ)=-3tan(θ)

tan (θ) sin (θ) - 4 tan (θ) = - 3 tan (θ)

θ = πn

Solution steps

tan (θ) sin (θ) - 4 tan (θ) = - 3 tan (θ)

Subtract

- 3 tan (θ)

from both sides

tan (θ) sin (θ) - tan (θ) = 0

Factor

tan (θ) sin (θ) - tan (θ) : tan (θ) (sin (θ) - 1)

tan (θ) (sin (θ) - 1) = 0

Solving each part separately

tan (θ) = 0 or sin (θ) - 1 = 0

tan (θ) = 0 : θ = πn

sin (θ) - 1 = 0 : θ = \frac{π}{2} + 2 πn

Combine all the solutions

θ = πn, θ = \frac{π}{2} + 2 πn

Since the equation is undefined for:

\frac{π}{2} + 2 πn

θ = πn

sec^{2} (x) + tan (x) - 3 = 0

sin (x) = - 0.5

cos (x) = \frac{- 2}{2}

sin^{2} (θ) + sin (θ) = 0

cos^{2} (θ) - sin^{2} (θ) = sin (θ) + 1
