cos (θ) = \frac{2}{3}

Allgemeine Lösung für

cos (θ) = \frac{2}{3}

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

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

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

cos (9 x) = 0

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

5 cot (θ) = - 6

cos (3 x - 9 x) = 0

7 sin^{2} (θ) + 15 sin (θ) + 8 = 0
