cos(θ)=0.139

cos (θ) = 0.139

θ = 1.43134 \dots + 2 πn, θ = 2 π - 1.43134 \dots + 2 πn

Solution steps

cos (θ) = 0.139

Apply trig inverse properties

θ = arccos (0.139) + 2 πn, θ = 2 π - arccos (0.139) + 2 πn

Show solutions in decimal form

θ = 1.43134 \dots + 2 πn, θ = 2 π - 1.43134 \dots + 2 πn

- \frac{2 3}{3} = sec (θ)

1 sin (3 0^{\circ}) = 1.7 sin (θ)

sin (x) = \pm \frac{1}{2}

30 = 211.49 - 20.96 cosh (0.03291765 x)

tan (θ) = \frac{2}{- 3}
