Allgemeine Lösung für

cos (θ) = - \frac{35}{6}

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

θ = arccos (- \frac{35}{6}) + 2 πn, θ = - arccos (- \frac{35}{6}) + 2 πn

θ = arccos (- \frac{35}{6}) + 2 πn, θ = - arccos (- \frac{35}{6}) + 2 πn

5 cos (x) + 2 sin (x) = 0

5 cos (x) + 2 sin (x) = 2

sin (2 θ) + sin (θ) + 2 cos (θ) + 1 = 0, 0 \leq θ \leq 2 π

4 sin (x) + 3 cos (x) = 4
