展开 (2000)/((s+1)(s+50)(s+100))

解答

展开

\frac{2000}{( s + 1 ) ( s + 50 ) ( s + 100 )}

\frac{2000}{s ^{3} + 151 s ^{2} + 5150 s + 5000}

求解步骤

\frac{2000}{( s + 1 ) ( s + 50 ) ( s + 100 )}

乘开

(s + 1) (s + 50) (s + 100) : s^{3} + 151 s^{2} + 5150 s + 5000

= \frac{2000}{s ^{3} + 151 s ^{2} + 5150 s + 5000}

e x p an d (1 + \frac{x}{4})^{3}

e x p an d \frac{50 ( 1 + 0.5 t )}{2 + 0.01 t}

e x p an d (x e^{x} + e^{x})^{2}

e x p an d (10 - 2)^{2}

e x p an d x^{5} - 10 + 3 (2 x^{0.2}) 3 x - 1 + 6
