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

expand

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

\frac{1 - e ^{- s}}{s + e ^{- s} s}

Solution steps

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

Expand

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

= \frac{1 - e ^{- s}}{s + e ^{- s} s}

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

\frac{( x + 1 )}{2 ( x - 1 ) ( 4 x + 1 )}

\frac{( x + 5 ) ^{2}}{3}

\frac{6 x ^{2} + 2}{( x ^{2} - 1 ) ^{3}}

\frac{( n + 1 ) ! \cdot 2}{n ( n + 1 )}
