cos(x)=-1/2 ,0<= x<2pi

cos (x) = - \frac{1}{2}, 0 \leq x < 2 π

x = \frac{2 π}{3}, x = \frac{4 π}{3}

Solution steps

cos (x) = - \frac{1}{2}, 0 \leq x < 2 π

General solutions for

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

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

Solutions for the range

0 \leq x < 2 π

x = \frac{2 π}{3}, x = \frac{4 π}{3}

tan (x) = - \frac{5}{12}

cos (x) = 0.63

cos (x) = 0.58

cos (x) = 0.41

cos (x) = 0.42
