Allgemeine Lösung für

cos (θ) = 0.98

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

θ = arccos (0.98) + 2 πn, θ = 2 π - arccos (0.98) + 2 πn

θ = arccos (0.98) + 2 πn, θ = 2 π - arccos (0.98) + 2 πn

sec^{2} (x) = 3 tan^{2} (x) - 1

csc (x) + cot (x) = \frac{3}{3}

sin (θ) + 1 = cos (θ)

2 sin^{2} (θ) - sin (θ) = 0

2 sin^{2} (x) = 2 - 3 cos (x)
