(d^2)/(dx^2)(x^{-2})

解答

\frac{d ^{2}}{d x ^{2}} (x^{- 2})

\frac{6}{x ^{4}}

求解步骤

\frac{d ^{2}}{d x ^{2}} (x^{- 2})

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

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

\frac{d}{d x} (- \frac{2}{x ^{3}}) = \frac{6}{x ^{4}}

= \frac{6}{x ^{4}}

\frac{d y}{d x} = - \frac{y ( x + y + 1 )}{x + 2 y}

\int \frac{1}{e ^{x} + 3} d x

d er i v a t i v e y = sin (x) ln (2 x)

\frac{d}{d x} (\frac{6 arctan ( 2 x )}{5 e ^{3 x}})
