Allgemeine Lösung für

cos (a) = 0.14

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

a = arccos (0.14) + 2 πn, a = 2 π - arccos (0.14) + 2 πn

a = arccos (0.14) + 2 πn, a = 2 π - arccos (0.14) + 2 πn

\frac{1 + cos ^{2} ( x )}{sin ^{2} ( x )} = \frac{1}{sin ^{2} ( x )}

7 sin (a) = \frac{1}{11}

tan (x) = 2, x + y = 135

tan (\frac{x}{2}) + cos (x) = 1
