arcsec (\frac{2}{2})

\frac{π}{4}

十进制

45

求解步骤

arcsec (\frac{2}{2})

使用以下普通恒等式:

arcsec (\frac{2}{2}) = \frac{π}{4}

arcsec (\frac{2}{2})

x 1 \frac{2 3}{3} 22 - 2 - 2 - \frac{2 3}{3} - 1 arcsec (x) 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} π arcsec (x) 0^{\circ} 3 0^{\circ} 4 5^{\circ} 6 0^{\circ} 12 0^{\circ} 13 5^{\circ} 15 0^{\circ} 18 0^{\circ}

= \frac{π}{4}

= \frac{π}{4}
