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

expand

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

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

Solution steps

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

Expand

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

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

2 (x^{2} - y^{2}) d x

\frac{d ^{2}}{d x ^{2}} ((y) (4 cos (3 x) + 6 sin (3 x)))

\frac{d}{d x} ((7 x^{2} - 5) e^{x}) - 5 x^{2}

\frac{2 ( 30 x ^{2} + 9 x - 20 )}{( 2 x + 1 ) ( 3 x ^{2} - 5 )}

f (x) ((x) = 4 x - 6)
