求解步骤

arccos (cos (\frac{π}{6}))

Use the inverse trig property:

\frac{π}{6}

arccos (cos (\frac{π}{6}))

对于

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

0 \leq \frac{π}{6} \leq π

= \frac{π}{6}

= \frac{π}{6}

\frac{2 cos ^{2} ( 4 5 ^{\circ} ) + 3 csc ( 3 7 ^{\circ} )}{2 tan ( 4 5 ^{\circ} )}

sin (2 arcsin (1))

sec (\frac{17 π}{4})

cos (arctan (\frac{5}{12}))

cos (7 5^{\circ}) cos (1 5^{\circ})
