2cos(θ)=-sqrt(3),0<= θ<2pi

2 cos (θ) = - 3, 0 \leq θ < 2 π

θ = \frac{5 π}{6}, θ = \frac{7 π}{6}

Solution steps

2 cos (θ) = - 3, 0 \leq θ < 2 π

Divide both sides by

2

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

Solutions for the range

0 \leq θ < 2 π

θ = \frac{5 π}{6}, θ = \frac{7 π}{6}

2 cos (3 θ) = - 3, 0 \leq θ \leq 2 π

csc (θ) = 10

cos (2 x) = \frac{2}{2}, (0, 2 π)

tan (2 x) = 2 tan (x)

- 4 cos (c) - 12 = 2 cos (c) - 6
