cos^2(θ)-sin^2(θ)=1

cos^{2} (θ) - sin^{2} (θ) = 1

θ = πn

Solution steps

cos^{2} (θ) - sin^{2} (θ) = 1

Rewrite using trig identities

cos (2 θ) = 1

General solutions for

cos (2 θ) = 1

2 θ = 0 + 2 πn

Solve

2 θ = 0 + 2 πn : θ = πn

θ = πn

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

cos^{3} (x) = cos^{3} (x) csc (x)

- \frac{1}{2} = sin (θ)

2 sin (2 x) + 3 = 2

csc (θ) = 11
