limit as x approaches 0 of (e^{-1/x})^x

解答

x \to 0 lim ((e^{- \frac{1}{x}})^{x})

\frac{1}{e}

十进制

0.36787 \dots

求解步骤

x \to 0 lim ((e^{- \frac{1}{x}})^{x})

(e^{- \frac{1}{x}})^{x} = \frac{1}{e}

= x \to 0 lim (\frac{1}{e})

x \to a lim c = c

= \frac{1}{e}

\int x e^{2 x y} d y

\frac{\partial}{\partial y} (3 x^{2} y + 4 x y^{2})

\int e^{- \frac{x}{10}} d x

\frac{d}{d x} (20 - 2 x)

\frac{d}{d x} (\frac{x ^{4}}{8} ln (x) - \frac{x ^{4}}{32})
