(d^2)/(dx^2)(1/(sqrt(x)))

解答

\frac{d ^{2}}{d x ^{2}} (\frac{1}{x})

\frac{3}{4 x ^{\frac{5}{2}}}

求解步骤

\frac{d ^{2}}{d x ^{2}} (\frac{1}{x})

\frac{d}{d x} (\frac{1}{x}) = - \frac{1}{2 x ^{\frac{3}{2}}}

= \frac{d}{d x} (- \frac{1}{2 x ^{\frac{3}{2}}})

\frac{d}{d x} (- \frac{1}{2 x ^{\frac{3}{2}}}) = \frac{3}{4 x ^{\frac{5}{2}}}

= \frac{3}{4 x ^{\frac{5}{2}}}

\frac{\partial}{\partial x} (\frac{y}{2 x + y})

\int \frac{sin ( t )}{t} d t

(y - x 4) d x + (x + y 4) d y = 0

\frac{d y}{d x} = 4 x e^{2 x}

\frac{\partial}{\partial x} (x + ln (5 x + y))
