cos (x) = 0.96

Allgemeine Lösung für

cos (x) = 0.96

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

x = arccos (0.96) + 2 πn, x = 2 π - arccos (0.96) + 2 πn

x = arccos (0.96) + 2 πn, x = 2 π - arccos (0.96) + 2 πn

2 sin (3 x) + 3 = 0

4 cos^{2} (θ) sin (θ) + 2 cos^{2} (θ) = 0

1 + cos (2 x) = 0

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

2 sin^{2} (x) + 1 = 4 sin (x)
