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

expand

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

\frac{1 - e ^{- 2 π s}}{s ^{4} + 5 s ^{2} + 4}

Solution steps

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

Expand

(s^{2} + 1) (s^{2} + 4) : s^{4} + 5 s^{2} + 4

= \frac{1 - e ^{- 2 π s}}{s ^{4} + 5 s ^{2} + 4}

\frac{7 e ^{x}}{( 7 + e ^{x} ) ^{2}}

a^{2} + (x + Δ x)^{2} - a^{2} + x^{2}

y (y^{2} + 1) d x + x (y^{2} - 1) ln (x) d y

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

\frac{3}{( 6 + x ) ^{3}}
