sin(θ)= 4/7

sin (θ) = \frac{4}{7}

θ = 0.60824 \dots + 2 πn, θ = π - 0.60824 \dots + 2 πn

Solution steps

sin (θ) = \frac{4}{7}

Apply trig inverse properties

θ = arcsin (\frac{4}{7}) + 2 πn, θ = π - arcsin (\frac{4}{7}) + 2 πn

Show solutions in decimal form

θ = 0.60824 \dots + 2 πn, θ = π - 0.60824 \dots + 2 πn

sin^{2} (θ) + 3 sin (θ) - 4 = 0

cos (2 θ) = \frac{2}{2}

4 cos (x) = 0

- \frac{1}{2} + cos^{2} (x) + cos^{2} (\frac{x}{2}) = 0

9 sin (2 x) sin (x) = 9 cos (x)
