Allgemeine Lösung für

cos (x) = 0.184

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

x = arccos (0.184) + 2 πn, x = 2 π - arccos (0.184) + 2 πn

x = arccos (0.184) + 2 πn, x = 2 π - arccos (0.184) + 2 πn

(10 cos (2 t + \frac{π}{6})) = 0

2 sin (x + 1.2) - 4.22 = - 4

- 23 sin (x) + 2 cos (x) = 0

2 cos (4 x) - 2 = 0
