derivative of-49sin(7x)

解

\frac{d}{d x} (- 49 sin (7 x))

解

- 343 cos (7 x)

解答ステップ

\frac{d}{d x} (- 49 sin (7 x))

定数を除去:

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

= - 49 \frac{d}{d x} (sin (7 x))

連鎖法則を適用:

cos (7 x) \frac{d}{d x} (7 x)

= cos (7 x) \frac{d}{d x} (7 x)

\frac{d}{d x} (7 x) = 7

= - 49 cos (7 x) \cdot 7

簡素化

= - 343 cos (7 x)
