cos(θ/2)=(sqrt(3))/2

cos (\frac{θ}{2}) = \frac{3}{2}

θ = \frac{π}{3} + 4 πn, θ = \frac{11 π}{3} + 4 πn

Solution steps

cos (\frac{θ}{2}) = \frac{3}{2}

General solutions for

cos (\frac{θ}{2}) = \frac{3}{2}

\frac{θ}{2} = \frac{π}{6} + 2 πn, \frac{θ}{2} = \frac{11 π}{6} + 2 πn

Solve

\frac{θ}{2} = \frac{π}{6} + 2 πn : θ = \frac{π}{3} + 4 πn

Solve

\frac{θ}{2} = \frac{11 π}{6} + 2 πn : θ = \frac{11 π}{3} + 4 πn

θ = \frac{π}{3} + 4 πn, θ = \frac{11 π}{3} + 4 πn

cos (x) = 0.3

2 cos^{2} (x) - 7 cos (x) + 3 = 0

sin (2 x) + cos (2 x) = 2

sin (a) = \frac{1}{2}

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