Allgemeine Lösung für

sin (x) = \frac{48 sin ( 6 9 ^{\circ} )}{47.5}

sin (x) = a \Rightarrow x = arcsin (a) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (a) + 36 0^{\circ} n

x = arcsin (\frac{48 sin ( 6 9 ^{\circ} )}{47.5}) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (\frac{48 sin ( 6 9 ^{\circ} )}{47.5}) + 36 0^{\circ} n

x = arcsin (\frac{48 sin ( 6 9 ^{\circ} )}{47.5}) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (\frac{48 sin ( 6 9 ^{\circ} )}{47.5}) + 36 0^{\circ} n

2 cos^{2} (3 x) + cos (3 x) - 1 = 0

sin (3 x) = \frac{- 3}{4}

4 cos (x - 4 5^{\circ}) + 7 = 10

cos^{2} (x) = 3 (1 - sin (x))

- 2 = 2 cos (3 θ)
