展开 ((K(s+0.5)))/s

解答

展开

\frac{( K ( s + 0.5 ) )}{s}

K + \frac{0.5 K}{s}

求解步骤

\frac{K ( s + 0.5 )}{s}

乘开

K (s + 0.5) : Ks + 0.5 K

= \frac{Ks + 0.5 K}{s}

使用分式法则:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{Ks + 0.5 K}{s} = \frac{Ks}{s} + \frac{0.5 K}{s}

= \frac{Ks}{s} + \frac{0.5 K}{s}

消掉

\frac{Ks}{s} : K

= K + \frac{0.5 K}{s}
