sin(arcsec(1))

解答

sin (arcsec (1))

0

求解步骤

sin (arcsec (1))

使用三角恒等式改写:

sin (arcsec (1)) = 1 - \frac{1}{1 ^{2}}

利用以下特性:

sin (arcsec (x)) = 1 - \frac{1}{x ^{2}}

= 1 - \frac{1}{1 ^{2}}

= 1 - \frac{1}{1 ^{2}}

化简

= 0

(29.7) cos (26. 8^{\circ}) (1.71) - 5 sin (3 0^{\circ}) (1.71)^{2}

arcsin (\frac{31 sin ( 2 0 ^{\circ} )}{12})

arcsin (\frac{sin ( 4 4 ^{\circ} ) \cdot 1.33}{1.53})

12.5 \cdot sin (53.1 3^{\circ}) + 12.5 \cdot sin (53.1 3^{\circ})

27 sin (7 0^{\circ})
