Allgemeine Lösung für

cos (x) = \frac{0.95293}{1.36156}

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

x = arccos (\frac{0.95293}{1.36156}) + 2 πn, x = 2 π - arccos (\frac{0.95293}{1.36156}) + 2 πn

x = arccos (\frac{0.95293}{1.36156}) + 2 πn, x = 2 π - arccos (\frac{0.95293}{1.36156}) + 2 πn

Zeige Lösungen in Dezimalform

x = 0.79556 \dots + 2 πn, x = 2 π - 0.79556 \dots + 2 πn

so l v e f or θ, W = F \cdot d \cdot cos (θ)

cos (\frac{π}{6} + x) + sin (\frac{π}{3} + x) = 0

2.55 = \frac{1}{tan ( x )}

tan (5 x) = cot (x)

\frac{1}{4} sin (8 x) = - \frac{1}{8}, 2 cos (8 x) = 3
