sec(θ)+4=4sec(θ)

sec (θ) + 4 = 4 sec (θ)

θ = 0.72273 \dots + 2 πn, θ = 2 π - 0.72273 \dots + 2 πn

Solution steps

sec (θ) + 4 = 4 sec (θ)

Solve by substitution

sec (θ) = \frac{4}{3}

sec (θ) = \frac{4}{3} : θ = arcsec (\frac{4}{3}) + 2 πn, θ = 2 π - arcsec (\frac{4}{3}) + 2 πn

Combine all the solutions

θ = arcsec (\frac{4}{3}) + 2 πn, θ = 2 π - arcsec (\frac{4}{3}) + 2 πn

Show solutions in decimal form

θ = 0.72273 \dots + 2 πn, θ = 2 π - 0.72273 \dots + 2 πn

sin (2 x) - 4 \cdot cos (x) = 0

5 tan (θ) + 3 = 0

sin (θ) = - \frac{4}{7}, π < θ < \frac{3 π}{2}, cos (2 θ)

tan (θ) = - \frac{2}{5}

(tan (x) - 1) (3 tan (x) + 1) = 0
