(\partial)/(\partial x)(sqrt(9-x))

解

\frac{\partial}{\partial x} (9 - x)

解

- \frac{1}{2 9 - x}

解答ステップ

\frac{\partial}{\partial x} (9 - x)

連鎖法則を適用:

\frac{1}{2 9 - x} \frac{\partial}{\partial x} (9 - x)

= \frac{1}{2 9 - x} \frac{\partial}{\partial x} (9 - x)

\frac{\partial}{\partial x} (9 - x) = - 1

= \frac{1}{2 9 - x} (- 1)

簡素化

= - \frac{1}{2 9 - x}
