Allgemeine Lösung für

cos (θ) = \frac{11}{61}

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

θ = arccos (\frac{11}{61}) + 2 πn, θ = 2 π - arccos (\frac{11}{61}) + 2 πn

θ = arccos (\frac{11}{61}) + 2 πn, θ = 2 π - arccos (\frac{11}{61}) + 2 πn

Zeige Lösungen in Dezimalform

θ = 1.38947 \dots + 2 πn, θ = 2 π - 1.38947 \dots + 2 πn

cos (x) = \frac{4}{8}

\frac{sin ( 5 1 ^{\circ} )}{18} = \frac{sin ( x )}{22}

cos (2 x) = sin (7 0^{\circ} + x)

tan (3 x) \cdot cot (x + 4 0^{\circ}) = 1

cos (x) = - \frac{1}{2} 2
