sin(θ)= 2/7

sin (θ) = \frac{2}{7}

θ = 0.28975 \dots + 2 πn, θ = π - 0.28975 \dots + 2 πn

Solution steps

sin (θ) = \frac{2}{7}

Apply trig inverse properties

θ = arcsin (\frac{2}{7}) + 2 πn, θ = π - arcsin (\frac{2}{7}) + 2 πn

Show solutions in decimal form

θ = 0.28975 \dots + 2 πn, θ = π - 0.28975 \dots + 2 πn

2 sec (x) - 5 = 0

tan (a) + cot (a) = sec (a) cos (a)

- 5 tan^{2} (θ) + 3 = 8 tan (θ) + 6

cos (θ) = \frac{- 3}{13}

cos (x) = 0.84
