expand 1/(s(s+1)(s+3))

expand

\frac{1}{s ( s + 1 ) ( s + 3 )}

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

Solution steps

\frac{1}{s ( s + 1 ) ( s + 3 )}

Expand

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

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

\frac{1}{2} (- \frac{1}{6} csc^{6} (2 x) + \frac{1}{4} csc^{4} (2 x))

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

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

(t am x + cot (x)) cos (2 x)

- B (x^{2} - x + 1)^{2}
