Allgemeine Lösung für

cos (θ) = 0.7071

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

θ = arccos (0.7071) + 2 πn, θ = 2 π - arccos (0.7071) + 2 πn

θ = arccos (0.7071) + 2 πn, θ = 2 π - arccos (0.7071) + 2 πn

2 cos (x) - 5 sin (x) = 0

sin (3 0^{\circ}) = cos (2 x)

3 sec (x) - cos (x) - 2 = 0

3 cos (3 t) = 0

18 cos (x) + 9 sin (2 x) = 0
