Allgemeine Lösung für

cos (x) = \frac{4.4}{6.5}

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

x = arccos (\frac{4.4}{6.5}) + 2 πn, x = 2 π - arccos (\frac{4.4}{6.5}) + 2 πn

x = arccos (\frac{4.4}{6.5}) + 2 πn, x = 2 π - arccos (\frac{4.4}{6.5}) + 2 πn

sin (θ) + 2 = \frac{2}{2}

sec (- 2 x) = - 2

tan (\frac{θ}{2} - \frac{π}{3}) = 1

sinh (x) = \frac{3}{4}

sin (θ) = 2 sin (θ) + 1
