expand 4/((s+1)(s^2+4))

expand

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

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

Solution steps

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

Expand

(s + 1) (s^{2} + 4) : s^{3} + 4 s + s^{2} + 4

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

\frac{e ^{- y}}{e ^{- y} - 2 ( e ^{y} - 2 )}

(- 3 x sin (t) + 3 y cos (t) + 5 t^{3}) d t

\frac{55 ( 19 1045 - 55 )}{486}

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

(0.12256 + 0.74486 i)^{4}
