Allgemeine Lösung für

cos (x) = \frac{308}{1475}

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

x = arccos (\frac{308}{1475}) + 2 πn, x = 2 π - arccos (\frac{308}{1475}) + 2 πn

x = arccos (\frac{308}{1475}) + 2 πn, x = 2 π - arccos (\frac{308}{1475}) + 2 πn

tan (θ) = \frac{6}{3}

csc (θ) = - \frac{13}{5}

cos (x) = 0.74

- 4 cos^{2} (x) + 6 cos (x) = 2

\frac{6}{π} - 4 sin (2 x) = 0
