cos (x + 4 0^{\circ}) = 0.85

Allgemeine Lösung für

cos (x + 4 0^{\circ}) = 0.85

cos (x) = a \Rightarrow x = arccos (a) + 36 0^{\circ} n, x = 36 0^{\circ} - arccos (a) + 36 0^{\circ} n

x + 4 0^{\circ} = arccos (0.85) + 36 0^{\circ} n, x + 4 0^{\circ} = 36 0^{\circ} - arccos (0.85) + 36 0^{\circ} n

x + 4 0^{\circ} = arccos (0.85) + 36 0^{\circ} n, x + 4 0^{\circ} = 36 0^{\circ} - arccos (0.85) + 36 0^{\circ} n

Löse

x + 4 0^{\circ} = arccos (0.85) + 36 0^{\circ} n : x = arccos (0.85) + 36 0^{\circ} n - 4 0^{\circ}

x + 4 0^{\circ} = arccos (0.85) + 36 0^{\circ} n
