Schritte zur Lösung

arccos (cos (\frac{7 π}{8}))

Use the inverse trig property:

\frac{7 π}{8}

arccos (cos (\frac{7 π}{8}))

Für

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

0 \leq \frac{7 π}{8} \leq π

= \frac{7 π}{8}

= \frac{7 π}{8}

8 cos (\frac{π}{3})

arctan (\frac{1}{20})

10 cos (0)

arctan (2.1)

\frac{1 + cos ( 3 0 ^{\circ} )}{2}
