Allgemeine Lösung für

cos (θ) = \frac{5}{11}

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

θ = arccos (\frac{5}{11}) + 2 πn, θ = 2 π - arccos (\frac{5}{11}) + 2 πn

θ = arccos (\frac{5}{11}) + 2 πn, θ = 2 π - arccos (\frac{5}{11}) + 2 πn

Zeige Lösungen in Dezimalform

θ = 1.09893 \dots + 2 πn, θ = 2 π - 1.09893 \dots + 2 πn

sin (t) = \frac{2}{2}

tan (x) sin^{2} (x) = 2 tan (x)

tan (\frac{x}{2}) = 0

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

cos (θ) = - \frac{1}{6}
