Wende die Eigenschaften der Trigonometrie an

cos (t) = \frac{21}{29}

Allgemeine Lösung für

cos (t) = \frac{21}{29}

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

t = arccos (\frac{21}{29}) + 2 πn, t = 2 π - arccos (\frac{21}{29}) + 2 πn

t = arccos (\frac{21}{29}) + 2 πn, t = 2 π - arccos (\frac{21}{29}) + 2 πn
