derivative of cot^3(x)

解

\frac{d}{d x} (cot^{3} (x))

解

- 3 cot^{2} (x) csc^{2} (x)

解答ステップ

\frac{d}{d x} (cot^{3} (x))

連鎖法則を適用:

3 (cot (x))^{2} \frac{d}{d x} (cot (x))

= 3 (cot (x))^{2} \frac{d}{d x} (cot (x))

\frac{d}{d x} (cot (x)) = - csc^{2} (x)

= 3 (cot (x))^{2} (- csc^{2} (x))

簡素化

= - 3 cot^{2} (x) csc^{2} (x)
