Allgemeine Lösung für

cos (x) = - \frac{7}{8}

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

x = arccos (- \frac{7}{8}) + 2 πn, x = - arccos (- \frac{7}{8}) + 2 πn

x = arccos (- \frac{7}{8}) + 2 πn, x = - arccos (- \frac{7}{8}) + 2 πn

sin (x) = - cos (2 x)

csc (\frac{π}{24} x) = 1

cos (x) = \frac{6}{18}

4 cos (2 x) + 10 sin (x) - 7 = 0

sin^{2} (x) + sin^{2} (x) = cos^{2} (x)
