Allgemeine Lösung für

cos (X) = 0.4848

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

X = arccos (0.4848) + 2 πn, X = 2 π - arccos (0.4848) + 2 πn

X = arccos (0.4848) + 2 πn, X = 2 π - arccos (0.4848) + 2 πn

X = 1.06466 \dots + 2 πn, X = 2 π - 1.06466 \dots + 2 πn

\frac{π}{3} = 3 + 2 sin (2 t)

1 + sin (2 x) = 5 (sin (x) + cos (x))

cos (2 x) = \frac{3}{4} - 5 cos^{2} (x)

sin (x + \frac{π}{9}) = \frac{3}{2}

3 cos (2 θ) = 3 sin (θ)
