3448*sin(8.56)

解答

3448 \cdot sin (8.56)

2623.75981 \dots

求解步骤

3448 sin (8.56)

整理为小数形式

= 2623.75981 \dots

1 + tan^{2} (4 5^{\circ})

0.099 (9.8) (cos (2 2^{\circ})) + 0.71 (cos (6 8^{\circ}))

cos (\frac{2 π}{15}) cos (\frac{π}{30}) - sin (\frac{2 π}{15}) sin (\frac{π}{30})

cos (65. 7^{\circ})

120 (tan (32. 3^{\circ}))
