cos (x) = \frac{5}{6}

Allgemeine Lösung für

cos (x) = \frac{5}{6}

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

x = arccos (\frac{5}{6}) + 2 πn, x = 2 π - arccos (\frac{5}{6}) + 2 πn

x = arccos (\frac{5}{6}) + 2 πn, x = 2 π - arccos (\frac{5}{6}) + 2 πn

Lösungen für den Bereich

\frac{3 π}{2} \leq x \leq 2 π

x = 2 π - arccos (\frac{5}{6})
