Allgemeine Lösung für

cos (θ) = 0.417

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

θ = arccos (0.417) + 2 πn, θ = 2 π - arccos (0.417) + 2 πn

θ = arccos (0.417) + 2 πn, θ = 2 π - arccos (0.417) + 2 πn

tan (x) = 2.7475

2 + 3 cot^{2} (θ) - 3 csc (θ) = 5

2 sin (6 x) + 2 sin (2 x) = 0

tan^{2} (2 x) - 1 = sec (2 x)

- 1.92 = cos (x)
