Allgemeine Lösung für

cos (x) = \frac{4}{35}

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

x = arccos (\frac{4}{35}) + 2 πn, x = 2 π - arccos (\frac{4}{35}) + 2 πn

x = arccos (\frac{4}{35}) + 2 πn, x = 2 π - arccos (\frac{4}{35}) + 2 πn

Zeige Lösungen in Dezimalform

x = 1.45626 \dots + 2 πn, x = 2 π - 1.45626 \dots + 2 πn

tan (x) = \frac{11}{13}

0.04 = 0.08 sin (x)

tan (x) = \frac{11}{18}

csc (A) \cdot tan (A) = sin (A)

cos (x) = \frac{2}{3}
