expand 1/((s+9)(s^2+k^2))

expand

\frac{1}{( s + 9 ) ( s ^{2} + k ^{2} )}

\frac{1}{s ^{3} + k ^{2} s + 9 s ^{2} + 9 k ^{2}}

Solution steps

\frac{1}{( s + 9 ) ( s ^{2} + k ^{2} )}

Expand

(s + 9) (s^{2} + k^{2}) : s^{3} + k^{2} s + 9 s^{2} + 9 k^{2}

= \frac{1}{s ^{3} + k ^{2} s + 9 s ^{2} + 9 k ^{2}}

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

(3 x^{2} - 1) d x

- sin (t) θ (t - \frac{π}{2})
