(\partial)/(\partial x)((mcT)/(wp(m,T,w,x)))

解答

\frac{\partial}{\partial x} (\frac{m c T}{w p ( m , T , w , x )})

- \frac{1}{p ( m , T , w , x ) ^{2}} \frac{\partial}{\partial x} (p (m, T, w, x))

求解步骤

\frac{\partial}{\partial x} (\frac{m c T}{w p ( m , T , w , x )})

将

c, m, T, w

视为常数

将常数提出:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{m c T}{w} \frac{\partial}{\partial x} (\frac{1}{p ( m , T , w , x )})

使用指数法则:

\frac{1}{a} = a^{- 1}

= \frac{m c T}{w} \frac{\partial}{\partial x} (p (m, T, w, x)^{- 1})

使用连锁律:

- \frac{1}{p ( m , T , w , x ) ^{2}} \frac{\partial}{\partial x} (p (m, T, w, x))

= - \frac{1}{p ( m , T , w , x ) ^{2}} \frac{\partial}{\partial x} (p (m, T, w, x))
