expand (e^{-s})/(s(s+1)^3)

expand

\frac{e ^{- s}}{s ( s + 1 ) ^{3}}

\frac{e ^{- s}}{s ^{4} + 3 s ^{3} + 3 s ^{2} + s}

Solution steps

\frac{e ^{- s}}{s ( s + 1 ) ^{3}}

(s + 1)^{3} = s^{3} + 3 s^{2} + 3 s + 1

= \frac{e ^{- s}}{s ( s ^{3} + 3 s ^{2} + 3 s + 1 )}

Expand

s (s^{3} + 3 s^{2} + 3 s + 1) : s^{4} + 3 s^{3} + 3 s^{2} + s

= \frac{e ^{- s}}{s ^{4} + 3 s ^{3} + 3 s ^{2} + s}

(x + 1) \cdot ln^{2} (x + 1)

K (1 + \frac{1}{I s} + d s)

e^{3 t} h (t - 1)

\frac{x ^{2} + 4}{x ^{2} ( x - 4 )}
