Allgemeine Lösung für

cos (θ) = \frac{43}{90}

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

θ = arccos (\frac{43}{90}) + 2 πn, θ = 2 π - arccos (\frac{43}{90}) + 2 πn

θ = arccos (\frac{43}{90}) + 2 πn, θ = 2 π - arccos (\frac{43}{90}) + 2 πn

8 cos (2 x - 5) = 3

\frac{116}{sin ( 9 0 ^{\circ} )} = \frac{4}{sin ( x )}

\frac{3}{cos ^{2} ( x )} = \frac{7 + 4}{cot ( x )}

sin (x) = 0.01

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