(\partial)/(\partial x)(x^2+y^2+10)

解

\frac{\partial}{\partial x} (x^{2} + y^{2} + 10)

2 x

解答ステップ

\frac{\partial}{\partial x} (x^{2} + y^{2} + 10)

y

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 x} (x^{2}) + \frac{\partial}{\partial x} (y^{2}) + \frac{\partial}{\partial x} (10)

\frac{\partial}{\partial x} (x^{2}) = 2 x

\frac{\partial}{\partial x} (y^{2}) = 0

\frac{\partial}{\partial x} (10) = 0

= 2 x + 0 + 0

簡素化

= 2 x
