-1/2 =cos(x)

- \frac{1}{2} = cos (x)

x = \frac{2 π}{3} + 2 πn, x = \frac{4 π}{3} + 2 πn

Solution steps

- \frac{1}{2} = cos (x)

Switch sides

cos (x) = - \frac{1}{2}

General solutions for

cos (x) = - \frac{1}{2}

x = \frac{2 π}{3} + 2 πn, x = \frac{4 π}{3} + 2 πn

cos (θ) = - \frac{2}{3}

8 tan (x) sin (x) = 7 sin (x)

cos (x) = 2 cos (x) - 1

sin^{3} (x) + cos^{3} (x) = 0

- sin (3 x) \cdot 3 = 0
