Schritte zur Lösung

arccos (cos (\frac{7 π}{9}))

Use the inverse trig property:

\frac{7 π}{9}

arccos (cos (\frac{7 π}{9}))

Für

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

0 \leq \frac{7 π}{9} \leq π

= \frac{7 π}{9}

= \frac{7 π}{9}

30 sin (4 5^{\circ})

tan (\frac{3 π}{5})

20 \cdot sin (6 0^{\circ})

cot (3 6^{\circ})

300 cos (3 0^{\circ})
