(d^2)/(dx^2)((x^2+8)^8)

解答

\frac{d ^{2}}{d x ^{2}} ((x^{2} + 8)^{8})

16 ((x^{2} + 8)^{7} + 14 x^{2} (x^{2} + 8)^{6})

求解步骤

\frac{d ^{2}}{d x ^{2}} ((x^{2} + 8)^{8})

\frac{d}{d x} ((x^{2} + 8)^{8}) = 16 x (x^{2} + 8)^{7}

= \frac{d}{d x} (16 x (x^{2} + 8)^{7})

\frac{d}{d x} (16 x (x^{2} + 8)^{7}) = 16 ((x^{2} + 8)^{7} + 14 x^{2} (x^{2} + 8)^{6})

= 16 ((x^{2} + 8)^{7} + 14 x^{2} (x^{2} + 8)^{6})

\frac{d}{d x} ((x - 1) ln ∣ x - 1 ∣)

\frac{\partial}{\partial x} (330.28 cos (23 x))

\int arctan (x) d x

\int sec^{4} (2 x) tan (2 x) d x
