cos (θ) = \frac{3}{5}

Allgemeine Lösung für

cos (θ) = \frac{3}{5}

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

θ = arccos (\frac{3}{5}) + 2 πn, θ = 2 π - arccos (\frac{3}{5}) + 2 πn

θ = arccos (\frac{3}{5}) + 2 πn, θ = 2 π - arccos (\frac{3}{5}) + 2 πn

Lösungen für den Bereich

\frac{3 π}{2} < θ < 2 π

θ = 2 π - arccos (\frac{3}{5})

cos (2 x) = \frac{3}{2}

- 3 cos (2 θ) + 2 sin (θ) + 5 = 9 sin (θ)

3 + sin (x) = 5 cos (2 x)

cos (x) = \frac{15}{20}

a sin (x) + b cos (x) = 0
