(d^2)/(dx^2)(7e^{-x^2})

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

- 14 (- 2 e^{- x^{2}} x^{2} + e^{- x^{2}})

Solution steps

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

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

= \frac{d}{d x} (- 14 e^{- x^{2}} x)

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

= - 14 (- 2 e^{- x^{2}} x^{2} + e^{- x^{2}})

\int \frac{x ^{2} + 2 x + 1}{2} sin (1.3 x) d x

\int_{1}^{e^{3}} x^{4} ln (x) d x

f (x) = ln (x e^{x} + 8)

7 x^{2} - y^{2} = 4

\frac{d}{d x} (y (x + 1))
