解答

arcsec (2) - arcsec (1)

\frac{π}{3}

十进制

60

求解步骤

arcsec (2) - arcsec (1)

使用以下普通恒等式:

arcsec (2) = \frac{π}{3}

arcsec (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}{3}

使用以下普通恒等式:

arcsec (1) = 0

arcsec (1)

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}

= 0

= \frac{π}{3} - 0

化简

= \frac{π}{3}

cot (\frac{1}{2})

arccos (\frac{12}{37})

1000 (15) (12) (5.8 \cdot 1 0^{- 5}) (sin (2 5^{\circ}))

sin (13 5^{\circ}) - tan (33 0^{\circ})

tan (2 (\frac{π}{6}))
