solvefor x,cos(x)=-1/2

solve for

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

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

Solution steps

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

x, θ = arctan (\frac{y}{x})

cos (x) tan (x) = 10 tan (x)

cos (2 x) = \frac{3}{5}

- 4 cos (2 x) = 0

x, arcsin (y) = arcsin (x) + \frac{π}{3}
