Allgemeine Lösung für

cos (x) = 0.914

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

x = arccos (0.914) + 2 πn, x = 2 π - arccos (0.914) + 2 πn

x = arccos (0.914) + 2 πn, x = 2 π - arccos (0.914) + 2 πn

x = 0.41776 \dots + 2 πn, x = 2 π - 0.41776 \dots + 2 πn

cos^{2} (x) + 1 = 0

cos (2 x + \frac{π}{6}) = \frac{1}{2}

(1.54)^{2} = 2 - 2 cos (x)

4 sec (x) + 8 = 0, 0^{\circ} \leq x \leq 36 0^{\circ}
