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

expand

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

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

Solution steps

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

Expand

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

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

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

1 + cos (x) (1 + cos (x))

(sec (a) - tan (a)) (sec (a) + tan (a))

y (y^{3} - x) d x + x (y^{3} + x) d y

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