cos (x) = \frac{1}{4}

Allgemeine Lösung für

cos (x) = \frac{1}{4}

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

x = arccos (\frac{1}{4}) + 2 πn, x = 2 π - arccos (\frac{1}{4}) + 2 πn

x = arccos (\frac{1}{4}) + 2 πn, x = 2 π - arccos (\frac{1}{4}) + 2 πn

Lösungen für den Bereich

0 \leq x \leq 2 π

x = arccos (\frac{1}{4}), x = 2 π - arccos (\frac{1}{4})

2 = 2 cos (t)

50 sin (4 5^{\circ}) = 600 sin (θ)

2 + 2 cos (x) = \frac{2}{1 + cos ( x )}

k sin (x) - c = 0

cos (x) = sin (x - \frac{π}{2})
