Schritte zur Lösung

arccos (cos (\frac{4 π}{7}))

Use the inverse trig property:

\frac{4 π}{7}

arccos (cos (\frac{4 π}{7}))

Für

0 \leq x \leq π, a rccos (cos (x)) = x

0 \leq \frac{4 π}{7} \leq π

= \frac{4 π}{7}

= \frac{4 π}{7}

arctan (tan (0))

\frac{14}{tan ( 4 9 ^{\circ} )}

arcsin (\frac{1}{4})

cos (2 arctan (- 2))

- cos (\frac{5 π}{3})
