sin(θ)=-0.2

sin (θ) = - 0.2

θ = - 0.20135 \dots + 2 πn, θ = π + 0.20135 \dots + 2 πn

Solution steps

sin (θ) = - 0.2

Apply trig inverse properties

θ = arcsin (- 0.2) + 2 πn, θ = π + arcsin (0.2) + 2 πn

Show solutions in decimal form

θ = - 0.20135 \dots + 2 πn, θ = π + 0.20135 \dots + 2 πn

6 cos (2 x) = 5

2 cos^{2} (2 x) = 1

sin (z) = \frac{1}{2}

sin (3 x) = \frac{- 1}{2}

4 cos^{2} (x) + 7 sin (x) - 2 = 0
