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

Lösung

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

Lösung

0

Schritte zur Lösung

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

Umformung für L'Hopital

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

Wende das L'Hopital Theorem an

= x \to 0 - lim \frac{- \frac{1}{x ^{2}}}{\frac{e ^{- \frac{1}{x}}}{x ^{2}}}

Vereinfache

\frac{- \frac{1}{x ^{2}}}{\frac{e ^{- \frac{1}{x}}}{x ^{2}}} : - e^{\frac{1}{x}}

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

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

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

Wende die Kettenregel für Grenzen an:

0

= - 0

Vereinfache

= 0
