1/2+cos(x)=0

\frac{1}{2} + cos (x) = 0

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

Solution steps

\frac{1}{2} + cos (x) = 0

Move

\frac{1}{2}

to the right side

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

- 63 cot (θ) + 1 = - 5

5 - 10 sin (2 x) = 0

x, cos (3 x) = 0

9 cos (2 θ) = 8

cos (2 θ) + 6 sin^{2} (θ) = 4, 0 \leq θ < 2 π
