Allgemeine Lösung für

cos (x) = - 0.34

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

x = arccos (- 0.34) + 2 πn, x = - arccos (- 0.34) + 2 πn

x = arccos (- 0.34) + 2 πn, x = - arccos (- 0.34) + 2 πn

2 sin^{2} (x) = 3 sin (x) - 1

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

sin (4 x) + 1 = cos (4 x)

tan (x) = \frac{36}{28}

tan (x) = - 2 sin (x)
