expand (e^{-2s}-e^{-4s}+s^2)/(s(s^2+1))

expand

\frac{e ^{- 2 s} - e ^{- 4 s} + s ^{2}}{s ( s ^{2} + 1 )}

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

Solution steps

\frac{e ^{- 2 s} - e ^{- 4 s} + s ^{2}}{s ( s ^{2} + 1 )}

Expand

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

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

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

- 2 (3 x^{2} - 8 x + 4)^{2}

e^{x} (1 + e^{- x})

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

X \cdot Y + λ (\frac{X}{4} + \frac{Y}{9} - 1)
