Allgemeine Lösung für

cos (x) = \frac{17.6}{26}

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

x = arccos (\frac{17.6}{26}) + 2 πn, x = 2 π - arccos (\frac{17.6}{26}) + 2 πn

x = arccos (\frac{17.6}{26}) + 2 πn, x = 2 π - arccos (\frac{17.6}{26}) + 2 πn

Zeige Lösungen in Dezimalform

x = 0.82722 \dots + 2 πn, x = 2 π - 0.82722 \dots + 2 πn

1 + 4 cos (θ) = 3 sin (θ), 0 \leq θ \leq 2 π

tan^{2} (x) + cot^{2} (x) = 1

sin (x) (1 - 2 cos (x)) = 0

4 cos^{2} (x) + 3 cos (x) = 1

sin (x) = 4 cos (x)
