Solution steps

cos (θ) = 0.8701

Apply trig inverse properties

cos (θ) = 0.8701

General solutions for

cos (θ) = 0.8701

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

θ = arccos (0.8701) + 2 πn, θ = 2 π - arccos (0.8701) + 2 πn

θ = arccos (0.8701) + 2 πn, θ = 2 π - arccos (0.8701) + 2 πn

Show solutions in decimal form

θ = 0.51539 \dots + 2 πn, θ = 2 π - 0.51539 \dots + 2 πn

cos (3 v) = cos (6), 0^{\circ} \leq v^{\circ} \leq 36 0^{\circ}

tan (x) = \frac{25.644}{106.372}

sin^{2} (θ) - 7 sin (θ) = 0

- 1 = 2 cos (2 θ)

tan (x) = \frac{10}{12}
