Allgemeine Lösung für

cos (x) = 0.12

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

x = arccos (0.12) + 2 πn, x = 2 π - arccos (0.12) + 2 πn

x = arccos (0.12) + 2 πn, x = 2 π - arccos (0.12) + 2 πn

cosh (z) = - 2

tan (\frac{θ}{2} + \frac{π}{3}) = - 1, 0 \leq θ < 2 π

- 9 cos^{2} (θ) + 13 = 20 sin (θ)

0 = sin (3 θ)

cos (x) = 1, 0 \leq x < 2 π
