cos(θ)=0.65

cos (θ) = 0.65

θ = 0.86321 \dots + 2 πn, θ = 2 π - 0.86321 \dots + 2 πn

Solution steps

cos (θ) = 0.65

Apply trig inverse properties

θ = arccos (0.65) + 2 πn, θ = 2 π - arccos (0.65) + 2 πn

Show solutions in decimal form

θ = 0.86321 \dots + 2 πn, θ = 2 π - 0.86321 \dots + 2 πn

- \frac{2}{3} sin (x) + \frac{1}{3} sin (2 x) = 0

cos (θ) = 0.84

cos (θ) = 0.88

cos (θ) = 0.76

cos (θ) = 0.25
