Allgemeine Lösung für

cos (x) = - \frac{3}{5}

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

x = arccos (- \frac{3}{5}) + 2 πn, x = - arccos (- \frac{3}{5}) + 2 πn

x = arccos (- \frac{3}{5}) + 2 πn, x = - arccos (- \frac{3}{5}) + 2 πn

tan (x) = - \frac{1}{3}

6 sin^{2} (θ) - sin (θ) - 2 = 0

tan (x) sin (x) + sin (x) = 0

2 sin (\frac{x}{5}) + 3 = 0

sin (\frac{θ}{2}) = 1
