(cos(x))/2-1/2 =0

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

x = 2 πn

Solution steps

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

Move

\frac{1}{2}

to the right side

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

Multiply both sides by

2

cos (x) = 1

General solutions for

cos (x) = 1

x = 0 + 2 πn

Solve

x = 0 + 2 πn : x = 2 πn

x = 2 πn

tan (x) = \frac{4}{7}

sin (x) = - \frac{8}{9}

cos^{2} (θ) + 2 cos (θ) = 3

cos^{2} (x) = \frac{1}{9}

sin^{4} (x) = sin^{4} (x) cos (x)
