Allgemeine Lösung für

cos (B) = \frac{3}{8}

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

B = arccos (\frac{3}{8}) + 2 πn, B = 2 π - arccos (\frac{3}{8}) + 2 πn

B = arccos (\frac{3}{8}) + 2 πn, B = 2 π - arccos (\frac{3}{8}) + 2 πn

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

4 sec^{2} (x) = 8

3 \cdot sin (x) - cos (x) = 2

cos (3 x) = sin (6 0^{\circ})

tan (x) + sec (x) = 3
