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

expand

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

\frac{1}{s ^{3} + s + s ^{2} + 1}

Solution steps

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

Expand

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

= \frac{1}{s ^{3} + s + s ^{2} + 1}

(1 + t e^{- t})^{3}

(x - 4) (x - 6) (x - 7) (x + 7)

(x - 2 y - 1) d x + (3 x - 6 y + 2) d y

(2 x + 1) y^{''} (x) + x y

\frac{d}{d y} ((f (y, x)) (x^{2} y + x + x y^{2} + y))
