Allgemeine Lösung für

cos (x) = \frac{2.9}{3.2}

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

x = arccos (\frac{2.9}{3.2}) + 2 πn, x = 2 π - arccos (\frac{2.9}{3.2}) + 2 πn

x = arccos (\frac{2.9}{3.2}) + 2 πn, x = 2 π - arccos (\frac{2.9}{3.2}) + 2 πn

cos (θ) sin (θ) - 3 cos (θ) = 0

csc (θ) = \frac{5}{3}

sin (3 0^{\circ}) = cos (x)

cos (9 x) (2 cos (x) + 1) = 0

cos (2 x - \frac{π}{4}) = 0, 0 \leq x \leq 2 π
