expand-d/(ds)((12(s+7))/((s^2-14s+13)^2))

expand

- \frac{d}{d s} (\frac{12 ( s + 7 )}{( s ^{2} - 14 s + 13 ) ^{2}})

- \frac{d}{d s} (\frac{12 s + 84}{( s ^{2} - 14 s + 13 ) ^{2}})

Solution steps

- \frac{d}{d s} (\frac{12 ( s + 7 )}{( s ^{2} - 14 s + 13 ) ^{2}})

Expand

12 (s + 7) : 12 s + 84

= - \frac{d}{d s} (\frac{12 s + 84}{( s ^{2} - 14 s + 13 ) ^{2}})

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

\frac{5 ( 5 - j x )}{10 - j x}

\frac{1}{( x ^{2} - 2 x - 5 ) ^{4}}

\frac{3 x ^{2} - 5 x - 52}{( x + 2 ) ( x - 4 ) ( x + 5 )}

3 sin (2 (π + θ))
