cos(θ)=-0.47

cos (θ) = - 0.47

θ = 2.06008 \dots + 2 πn, θ = - 2.06008 \dots + 2 πn

Degrees

θ = 118.03429 \dots^{\circ} + 36 0^{\circ} n, θ = - 118.03429 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (θ) = - 0.47

Apply trig inverse properties

cos (θ) = - 0.47

General solutions for

cos (θ) = - 0.47

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

θ = arccos (- 0.47) + 2 πn, θ = - arccos (- 0.47) + 2 πn

θ = arccos (- 0.47) + 2 πn, θ = - arccos (- 0.47) + 2 πn

Show solutions in decimal form

θ = 2.06008 \dots + 2 πn, θ = - 2.06008 \dots + 2 πn

1 + tan^{2} (x) cos (x) = sec (x)

sec (θ) = \frac{6}{2}

sin^{2} (x) + cos^{2} (x) = sin (x) csc^{2} (x)

1.5 2 = 3 cos (x)

\frac{sin ( 5 9 ^{\circ} )}{8} = \frac{sin ( x )}{9.25}
