Solution steps

cos (5 x) = - \frac{1}{2}

General solutions for

cos (5 x) = - \frac{1}{2}

5 x = \frac{2 π}{3} + 2 πn, 5 x = \frac{4 π}{3} + 2 πn

Solve

5 x = \frac{2 π}{3} + 2 πn : x = \frac{2 π}{15} + \frac{2 πn}{5}

Solve

5 x = \frac{4 π}{3} + 2 πn : x = \frac{4 π}{15} + \frac{2 πn}{5}

x = \frac{2 π}{15} + \frac{2 πn}{5}, x = \frac{4 π}{15} + \frac{2 πn}{5}
