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

expand

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

\frac{s + 1}{s ^{4} + 9 s ^{2}}

Solution steps

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

Expand

s^{2} (s^{2} + 9) : s^{4} + 9 s^{2}

= \frac{s + 1}{s ^{4} + 9 s ^{2}}

\frac{x ^{2} + 2 x - 5}{( x + 5 ) ( x + 2 )}

(83.98 - 62.98 i) (0, 4 - 6 i)

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

\frac{d}{d x} (e^{(20 + 0.5 i) \cdot x})

(1 - cos (x)) d x - (1 - cos (y)) d y
