Allgemeine Lösung für

sin (x) = - 0.397

sin (x) = - a \Rightarrow x = arcsin (- a) + 2 πn, x = π + arcsin (a) + 2 πn

x = arcsin (- 0.397) + 2 πn, x = π + arcsin (0.397) + 2 πn

x = arcsin (- 0.397) + 2 πn, x = π + arcsin (0.397) + 2 πn

2 cos (x) \cdot tan (x) - 1 = 0

sin (x) = - 0.465

cos (x) = \frac{10}{17}

so l v e f or θ, r = \frac{7}{1 + cos ( θ )}

3 cos (2 θ) + 5 cos (θ) + 2 = 0
