(d^2)/(dx^2)(3sqrt(x)-7/x)

\frac{d ^{2}}{d x ^{2}} (3 x - \frac{7}{x})

\frac{- 3 x ^{\frac{5}{2}} - 56 x}{4 x ^{4}}

Solution steps

\frac{d ^{2}}{d x ^{2}} (3 x - \frac{7}{x})

\frac{d}{d x} (3 x - \frac{7}{x}) = \frac{3 x ^{\frac{3}{2}} + 14}{2 x ^{\frac{3}{2}} x}

= \frac{d}{d x} (\frac{3 x ^{\frac{3}{2}} + 14}{2 x ^{\frac{3}{2}} x})

\frac{d}{d x} (\frac{3 x ^{\frac{3}{2}} + 14}{2 x ^{\frac{3}{2}} x}) = \frac{- 3 x ^{\frac{5}{2}} - 56 x}{4 x ^{4}}

= \frac{- 3 x ^{\frac{5}{2}} - 56 x}{4 x ^{4}}

\frac{d}{d x} (ln (\frac{3 x}{x + 2}))

\frac{d}{d x} (32 cos (2 x))

x \to - 2 lim (3)

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

\int_{1}^{2} x e^{x^{2}} d x
