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

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

e^{- \frac{x ^{2}}{2}} x^{2} - e^{- \frac{x ^{2}}{2}}

Solution steps

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

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

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

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

= e^{- \frac{x ^{2}}{2}} x^{2} - e^{- \frac{x ^{2}}{2}}

\frac{d ^{3}}{d x ^{3}} (sin (x))

x \to 0 + lim (tan (4 x))

\frac{4}{x ^{7}}

18 - 2 x

f (x) = 2^{x}
