展开 d/(dv)((p(v))(p(v)+(5.9)/(v^2)))+(v-1.7)

解答

展开

\frac{d}{d v} ((p (v)) (p (v) + \frac{5.9}{v ^{2}})) + (v - 1.7)

\frac{d}{d v} (p (v)^{2} + \frac{5.9 p ( v )}{v ^{2}}) + v - 1.7

求解步骤

\frac{d}{d v} ((p (v)) (p (v) + \frac{5.9}{v ^{2}})) + (v - 1.7)

去除括号:

(a) = a

= \frac{d}{d v} (p (v) (p (v) + \frac{5.9}{v ^{2}})) + v - 1.7

乘开

p (v) (p (v) + \frac{5.9}{v ^{2}}) : p (v)^{2} + \frac{5.9 p ( v )}{v ^{2}}

= \frac{d}{d v} (\frac{5.9 p ( v )}{v ^{2}} + p (v)^{2}) + v - 1.7
