cos(θ)=(-sqrt(3))/2

cos (θ) = \frac{- 3}{2}

θ = \frac{5 π}{6} + 2 πn, θ = \frac{7 π}{6} + 2 πn

Solution steps

cos (θ) = \frac{- 3}{2}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

cos (θ) = - \frac{3}{2}

General solutions for

cos (θ) = - \frac{3}{2}

θ = \frac{5 π}{6} + 2 πn, θ = \frac{7 π}{6} + 2 πn

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

cos (x) = \frac{5}{8}

tan (x) = cos (x)

cot (3 x) = 1

2 cos^{2} (t) - cos (t) = 0
