expand 3/((s+1)(s+2)^2)

expand

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

\frac{3}{s ^{3} + 5 s ^{2} + 8 s + 4}

Solution steps

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

(s + 2)^{2} = s^{2} + 4 s + 4

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

Expand

(s + 1) (s^{2} + 4 s + 4) : s^{3} + 5 s^{2} + 8 s + 4

= \frac{3}{s ^{3} + 5 s ^{2} + 8 s + 4}

sin (\frac{( 2 x - 1 ) π}{2})

0.502348 (- cos (θ) + 1)

- 2 (\frac{1}{5} + 5 k)

\frac{d}{d q} ((R (q)) (R (q) (q^{4} + 1)^{5}))

(2 sin (x) + 1) (cos (x) + 1)
