Allgemeine Lösung für

cos (θ) = 0.8126

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

θ = arccos (0.8126) + 2 πn, θ = 2 π - arccos (0.8126) + 2 πn

θ = arccos (0.8126) + 2 πn, θ = 2 π - arccos (0.8126) + 2 πn

Zeige Lösungen in Dezimalform

θ = 0.62219 \dots + 2 πn, θ = 2 π - 0.62219 \dots + 2 πn

cos (θ) = - \frac{4}{5}, tan (θ) < 0

16 sin^{2} (x) = 8

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

csc^{2} (x) = 5 csc (x) + 6

tan (θ) = 1770
