cos(θ)=(sqrt(3))/3

cos (θ) = \frac{3}{3}

θ = 0.95531 \dots + 2 πn, θ = 2 π - 0.95531 \dots + 2 πn

Solution steps

cos (θ) = \frac{3}{3}

Apply trig inverse properties

θ = arccos (\frac{3}{3}) + 2 πn, θ = 2 π - arccos (\frac{3}{3}) + 2 πn

Show solutions in decimal form

θ = 0.95531 \dots + 2 πn, θ = 2 π - 0.95531 \dots + 2 πn

arctan (x + 1) + arctan (x - 1) = arctan (2)

2 sin^{2} (x) - 2 sin (x) = 0

sin (2 x) = - 2 cos (x)

cos^{3} (x) + cos^{2} (x) - cos (x) = 1

6 sin (2 x) sin (x) = 6 cos (x)
