(d^2)/(dx^2)(3csc(x))

解答

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

- 3 csc (x) + 6 csc^{3} (x)

求解步骤

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

\frac{d}{d x} (3 csc (x)) = - 3 cot (x) csc (x)

= \frac{d}{d x} (- 3 cot (x) csc (x))

\frac{d}{d x} (- 3 cot (x) csc (x)) = - 3 csc (x) + 6 csc^{3} (x)

= - 3 csc (x) + 6 csc^{3} (x)
