Allgemeine Lösung für

cos (θ) = - 0.02

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

θ = arccos (- 0.02) + 2 πn, θ = - arccos (- 0.02) + 2 πn

θ = arccos (- 0.02) + 2 πn, θ = - arccos (- 0.02) + 2 πn

cos^{2} (2 x) = 3 cos (2 x)

cos (θ) = - 0.42

sin (\frac{θ}{2}) + cos (θ) = 1

3 sin (\frac{π}{5} x) = 2
