Allgemeine Lösung für

cos (x) = - 0.58

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

x = arccos (- 0.58) + 2 πn, x = - arccos (- 0.58) + 2 πn

x = arccos (- 0.58) + 2 πn, x = - arccos (- 0.58) + 2 πn

x = 2.18952 \dots + 2 πn, x = - 2.18952 \dots + 2 πn

tan^{4} (x) - 4 tan^{2} (x) + 3 = 0

sin (2 x) = \frac{21}{25}

csc^{2} (x) = sin (x)

tan (θ) = \frac{4}{2}

cos (x) \cdot sec (x) \cdot cot^{2} (x) = csc^{2} (x)
