Allgemeine Lösung für

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

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

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

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

11 csc (x) + 15 = 9 csc (x) + 19

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

\frac{( sin ( x ) + tan ( x ) )}{1 + cos ( x )} = m \cdot sec (x)

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