(\partial)/(\partial y)(x+4y)

解

\frac{\partial}{\partial y} (x + 4 y)

解

4

解答ステップ

\frac{\partial}{\partial y} (x + 4 y)

x

を定数として扱う

和/差の法則を適用:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (x) + \frac{\partial}{\partial y} (4 y)

\frac{\partial}{\partial y} (x) = 0

\frac{\partial}{\partial y} (4 y) = 4

= 0 + 4

簡素化

= 4
