cos(θ)=-0.076

cos (θ) = - 0.076

θ = 1.64686 \dots + 2 πn, θ = - 1.64686 \dots + 2 πn

Solution steps

cos (θ) = - 0.076

Apply trig inverse properties

θ = arccos (- 0.076) + 2 πn, θ = - arccos (- 0.076) + 2 πn

Show solutions in decimal form

θ = 1.64686 \dots + 2 πn, θ = - 1.64686 \dots + 2 πn

4 cos^{2} (θ) = 2, 0 \leq θ \leq 2 π

sin (θ) = \frac{21}{29}

3 tan (θ) + sec^{2} (θ) = 5

tan (t) = - \frac{3}{4}

sin (x) = - 0.47
