expand (e^{-s}(1+s))/(s^2(s+2))

expand

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

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

Solution steps

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

Expand

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

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

Expand

e^{- s} (1 + s) : e^{- s} + e^{- s} s

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

\frac{3 s + 1}{s ( s + 1 ) ( 2 s + 1 )}

(1 - sin^{2} (x))^{3}

2^{(x - 1)^{2}}

l imh \Rightarrow 0 (8 + h) 13 - 2 h

\frac{2 cos ( x )}{( 1 - sin ( x ) ) ^{2}}
