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

expand

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

\frac{1 - e ^{- 2 s}}{s ^{3} + 4 s}

Solution steps

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

Expand

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

= \frac{1 - e ^{- 2 s}}{s ^{3} + 4 s}

H (x - 2) (t - 2)^{2}

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

(1 - cos (θ))^{2} + sin^{2} (θ)

(4 x - 1) ln (2)

\frac{( 1 - t ) b \cdot d}{b ( 1 - t ) + c}
