(\partial)/(\partial x)(sin(8x-9y))

解

\frac{\partial}{\partial x} (sin (8 x - 9 y))

解

cos (8 x - 9 y) \cdot 8

解答ステップ

\frac{\partial}{\partial x} (sin (8 x - 9 y))

y

を定数として扱う

連鎖法則を適用:

cos (8 x - 9 y) \frac{\partial}{\partial x} (8 x - 9 y)

= cos (8 x - 9 y) \frac{\partial}{\partial x} (8 x - 9 y)

\frac{\partial}{\partial x} (8 x - 9 y) = 8

= cos (8 x - 9 y) \cdot 8
