Allgemeine Lösung für

cos (x) = - 0.564

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

x = arccos (- 0.564) + 2 πn, x = - arccos (- 0.564) + 2 πn

x = arccos (- 0.564) + 2 πn, x = - arccos (- 0.564) + 2 πn

6 sin (\frac{θ}{2}) = 6 cos (\frac{θ}{2})

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

sin (2 x) + 2 cos (x) = 0, 0 \leq x \leq 2 π

cos (x) = \frac{8.5}{9.9}

cos^{3} (x) = - cos^{2} (x)
