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

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

\frac{1}{2}

Decimal

0.5

Solution steps

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

Simplify

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

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

Apply L'Hopital's Rule

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

Apply L'Hopital's Rule

= x \to 0 - lim (\frac{e ^{x}}{e ^{x} x + 2 e ^{x}})

Plug in the value

x = 0

= \frac{e ^{0}}{e ^{0} \cdot 0 + 2 e ^{0}}

Simplify

= \frac{1}{2}
