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

Lösung

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

\frac{- x ^{\frac{5}{2}} - 16 x}{4 x ^{4}}

Schritte zur Lösung

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

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

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

\frac{d}{d x} (\frac{x ^{\frac{3}{2}} + 4}{2 x ^{\frac{3}{2}} x}) = \frac{- x ^{\frac{5}{2}} - 16 x}{4 x ^{4}}

= \frac{- x ^{\frac{5}{2}} - 16 x}{4 x ^{4}}

\frac{\partial}{\partial y} (x^{2} - x y - y^{2})

\int \frac{3 x ^{3} - x}{x} d x

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

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

x \to 2 lim (2 x^{2} + 1)
