Allgemeine Lösung für

cos (θ) = \frac{1}{4}

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

θ = arccos (\frac{1}{4}) + 2 πn, θ = 2 π - arccos (\frac{1}{4}) + 2 πn

θ = arccos (\frac{1}{4}) + 2 πn, θ = 2 π - arccos (\frac{1}{4}) + 2 πn

\frac{36}{sin ( 11 0 ^{\circ} )} = \frac{15}{sin ( x )}

6 sin (\frac{x}{2}) + 6 cos (x) = 0

cos (x) = 0.925

\frac{sin ( A )}{9} = \frac{sin ( 10 8 ^{\circ} )}{6}

sin (3 x - 6^{\circ}) = \frac{1}{2}
