展开 v(24,-3,12,0)yv(6,-3,5,-4)

解答

展开

v (24, - 3, 12, 0) y v (6, - 3, 5, - 4)

24 vv y, 6, - 24 vv y, 3, 5, - 24 vv y, 4 - 3 vv y, 12, 0 \cdot 6, 3, 12, 0 \cdot 3, 5, 3, 12, 0 \cdot 4

求解步骤

v (24, - 3, 12, 0) y v (6, - 3, 5, - 4)

= (24, - 3 \cdot 12 \cdot 0,,) (6, - 3 \cdot 5,, - 4) vv y

乘开

(24, - 3, 12, 0) (6, - 3, 5, - 4) : 24, 6, - 24, 3, 5, - 24, 4 - 3, 12, 0 \cdot 6, 3, 12, 0 \cdot 3, 5, 3, 12, 0 \cdot 4

= v y v (24, 6, - 24, 3, 5, - 24, 4 - 3, 12, 0 \cdot 6, 3, 12, 0 \cdot 3, 5, 3, 12, 0 \cdot 4)

乘开

v y v (24, 6, - 24, 3, 5, - 24, 4 - 3, 12, 0 \cdot 6, 3, 12, 0 \cdot 3, 5, 3, 12, 0 \cdot 4) : 24 vv y, 6, - 24 vv y, 3, 5, - 24 vv y, 4 - 3 vv y, 12, 0 \cdot 6, 3, 12, 0 \cdot 3, 5, 3, 12, 0 \cdot 4

= 24 vv y, 6, - 24 vv y, 3, 5, - 24 vv y, 4 - 3 vv y, 12, 0 \cdot 6, 3, 12, 0 \cdot 3, 5, 3, 12, 0 \cdot 4

e x p an d (\frac{1}{1 - 2 x})^{2}

e x p an d (x, y) (x - 3 y + 4)

e x p an d \frac{1200}{( 2000 + d ) ^{2}}

e x p an d cos (3 (t - π))

e x p an d \frac{2 ( 4 n - 2 )}{2 n + 5}
