Allgemeine Lösung für

cos (x) = 0.98

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

x = arccos (0.98) + 2 πn, x = 2 π - arccos (0.98) + 2 πn

x = arccos (0.98) + 2 πn, x = 2 π - arccos (0.98) + 2 πn

tan (3 x + \frac{π}{2}) = - 1

tan (θ) = \frac{m ^{2} - m ^{1}}{1 + m ^{2} \cdot m ^{1}}, m^{2}

tan^{2} (x) = 3 - 2 tan (x)

tan (3 x) + tan (5 x) = 0

sin (x) = \frac{1}{2} 3
