Allgemeine Lösung für

cos (x) = - \frac{1}{5}

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

x = arccos (- \frac{1}{5}) + 2 πn, x = - arccos (- \frac{1}{5}) + 2 πn

x = arccos (- \frac{1}{5}) + 2 πn, x = - arccos (- \frac{1}{5}) + 2 πn

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

7 sin (B) + 23 = 0

cos^{2} (3 x) = 1

tan (\frac{π}{4} - x) + cot (\frac{π}{4} - x) = 4

7 sin (θ) - 1 = 5 sin (θ)
