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

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

x = \frac{2 π}{3}, x = \frac{4 π}{3}

Solution steps

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

x = \frac{2 π}{3}, x = \frac{4 π}{3}

cot^{2} (θ) + cot (θ) - 20 = 0

cos (2 x) + 2 cos (x) + 1 = 0

sin^{2} (x) + 1 = cos^{2} (x)

arcsin (x) = \frac{π}{2}

sin (θ) = 0.6
