Allgemeine Lösung für

cos (x) = \frac{86.6}{100}

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

x = arccos (\frac{86.6}{100}) + 2 πn, x = 2 π - arccos (\frac{86.6}{100}) + 2 πn

x = arccos (\frac{86.6}{100}) + 2 πn, x = 2 π - arccos (\frac{86.6}{100}) + 2 πn

- 6 sin (θ) = - 33

sin (d) = 0.81

so l v e f or t, 16 sin (t) cos (t) = 6 sin (t)

6 cos (6 t) + 24 sin (6 t) = 0

sin (x) = \frac{50 \cdot sin ( 14 5 ^{\circ} )}{120}
