Allgemeine Lösung für

cos (θ) = - \frac{5}{6}

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

θ = arccos (- \frac{5}{6}) + 2 πn, θ = - arccos (- \frac{5}{6}) + 2 πn

θ = arccos (- \frac{5}{6}) + 2 πn, θ = - arccos (- \frac{5}{6}) + 2 πn

tan (θ) = - \frac{5}{12}

- 6 sin (θ) - 3 = sin (θ) + 4

- 9 cos^{2} (θ) + 23 sin (θ) + 17 = - 2

24 arcsin (x) = 4 π

cos (x) - 1 = sin (x)
