(110sqrt(2))/pi(1+cos(7854))

解答

\frac{110 \cdot 2}{π} \cdot (1 + cos (785 4^{\circ}))

69.65793 \dots

求解步骤

\frac{110 2}{18 0 ^{\circ}} (1 + cos (785 4^{\circ}))

整理为小数形式

= 69.65793 \dots

arcsin (- \frac{4}{7})

\frac{0.1 cos ( 0.1 ) - sin ( 0.1 )}{0.1 - sin ( 0.1 )}

2 \cdot sin (5 3^{\circ})

\frac{50 sin ( 1 5 ^{\circ} )}{400}

sin^{2} (3 2^{\circ}) + cos^{2} (5 8^{\circ})
