Allgemeine Lösung für

sin (θ) = - 0.9

sin (x) = - a \Rightarrow x = arcsin (- a) + 2 πn, x = π + arcsin (a) + 2 πn

θ = arcsin (- 0.9) + 2 πn, θ = π + arcsin (0.9) + 2 πn

θ = arcsin (- 0.9) + 2 πn, θ = π + arcsin (0.9) + 2 πn

cos (2 T) = 1, 0 \leq T \leq 2 π

2 - 2 cos^{2} (\frac{x}{2}) = 2 cos^{2} (x)

sec^{2} (θ) - 2 = tan^{2} (θ)

cos (x) = sin (x) + 1

2 sin^{2} (θ) = 3 (1 - cos (- θ))
