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

expand

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

\frac{s - e ^{- 2 π s} s}{s ^{2} + 4}

Solution steps

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

Expand

s (1 - e^{- 2 π s}) : s - e^{- 2 π s} s

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

\frac{sin ( z )}{z ^{2} \cdot ( z - 4 )}

e^{x} (e^{y} + 2 y e^{- x})

\frac{d}{d x} ((z) (x + 2 y + z - 2 x y z))

(2 e + 4)^{2}
