cos(θ)=sqrt(3/4)

cos (θ) = \frac{3}{4}

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

Solution steps

cos (θ) = \frac{3}{4}

Simplify

\frac{3}{4} : \frac{3}{2}

General solutions for

cos (θ) = \frac{3}{2}

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

2 sec (4 x) - 2 = 0

A, y = - 6 cos (A) - 2 sin^{2} (A)

2 cos (x^{2}) - 1 = 0

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