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

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

\frac{1}{e}

Decimal

0.36787 \dots

Solution steps

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

Simplify

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

Apply exponent rules

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

Apply the Limit Chain Rule:

\frac{1}{e}

= \frac{1}{e}

\frac{x}{3 x ^{2} + 4} - \frac{1}{4}

\int \frac{4 x ^{2} - 8 x}{( x - 1 ) ^{2} ( x ^{2} + 1 ) ^{2}} d x

\int sin (x) (1 - cos (x)) d x

\frac{d}{d x} (\frac{x ^{2} - 6 x}{1 + cos ( x )})

\int \frac{1}{x ^{2} + 4 x + 25} d x
