解答

展开

(0.5 s + 1) (4.04 s^{'} + 1) (0.3 s + 1)

0.606 s^{2} s' + 0.15 s^{2} + 3.232 ss' + 0.8 s + 4.04 s' + 1

求解步骤

(0.5 s + 1) (4.04 s^{'} + 1) (0.3 s + 1)

乘开

(0.5 s + 1) (4.04 s^{'} + 1) : 2.02 s s^{'} + 0.5 s + 4.04 s^{'} + 1

= (2.02 s s^{'} + 0.5 s + 4.04 s^{'} + 1) (0.3 s + 1)

乘开

(2.02 s s^{'} + 0.5 s + 4.04 s^{'} + 1) (0.3 s + 1) : 0.606 s^{2} s^{'} + 0.15 s^{2} + 3.232 s s^{'} + 0.8 s + 4.04 s^{'} + 1

= 0.606 s^{2} s^{'} + 0.15 s^{2} + 3.232 s s^{'} + 0.8 s + 4.04 s^{'} + 1

e x p an d (x + 3)^{3}

e x p an d (- G^{1} H^{1}) (- G^{3} H^{2})

e x p an d \frac{1}{3} (n^{3} + 3 n^{2} + 5 n + 3)

e x p an d \frac{1}{( 2 + 3 x ) ^{3}}
