cos(θ)-sqrt(cos(θ))=0

cos (θ) - cos (θ) = 0

θ = 2 πn, θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

Solution steps

cos (θ) - cos (θ) = 0

Solve by substitution

cos (θ) = 1, cos (θ) = 0

cos (θ) = 1 : θ = 2 πn

cos (θ) = 0 : θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

Combine all the solutions

θ = 2 πn, θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

2 sin^{2} (x) = \frac{csc ^{2} ( x )}{2}

4 sin^{2} (x) + 4 sin (x) = 1

5 cos (t) = 0

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

cos (x) = \frac{6}{10}
