cos(θ)=-0.44

cos (θ) = - 0.44

θ = 2.02639 \dots + 2 πn, θ = - 2.02639 \dots + 2 πn

Solution steps

cos (θ) = - 0.44

Apply trig inverse properties

θ = arccos (- 0.44) + 2 πn, θ = - arccos (- 0.44) + 2 πn

Show solutions in decimal form

θ = 2.02639 \dots + 2 πn, θ = - 2.02639 \dots + 2 πn

cos (θ) = - 0.62

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

cos (4 x) sin (x) = 0

3 cos (3 θ) = 0

3 cot (\frac{π}{2} x) = - 3
