arcsin(((sqrt(2)))/2)

解答

arcsin (\frac{( 2 )}{2})

\frac{π}{4}

十进制

45

求解步骤

arcsin (\frac{( 2 )}{2})

= arcsin (\frac{2}{2})

使用以下普通恒等式:

arcsin (\frac{2}{2}) = \frac{π}{4}

arcsin (\frac{2}{2})

x 0 \frac{1}{2} \frac{2}{2} \frac{3}{2} 1 arcsin (x) 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} arcsin (x) 0^{\circ} 3 0^{\circ} 4 5^{\circ} 6 0^{\circ} 9 0^{\circ}

= \frac{π}{4}

= \frac{π}{4}

\frac{sin ( 6 0 ^{\circ} )}{sin ( 3 0 ^{\circ} )}

tan (\frac{5}{6} π)

2 sin (π) - 1

csc (\frac{22 π}{3})

10 cos (27 0^{\circ})
