limit as x approaches 0+of 1/(xln(x))

x \to 0 + lim (\frac{1}{x ln ( x )})

- \infty

Solution steps

x \to 0 + lim (\frac{1}{x ln ( x )})

\frac{1}{x ln ( x )} = \frac{1}{x} \cdot \frac{1}{ln ( x )}

= x \to 0 + lim (\frac{1}{x} \cdot \frac{1}{ln ( x )})

Rewrite for L'Hopital

= x \to 0 + lim \frac{\frac{1}{x}}{\frac{1}{\frac{1}{l n ( x )}}}

Apply L'Hopital's Rule

: x \to 0 + lim (\frac{- \frac{1}{x ^{2}}}{\frac{1}{x}})

= x \to 0 + lim (\frac{- \frac{1}{x ^{2}}}{\frac{1}{x}})

Simplify

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

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

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

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

For

x

approaching

0

from the right

, x > 0 \Rightarrow x > 0

The denominator is a positive quantity approaching 0 from the right

= - \infty

\int \frac{1}{x ^{6}} + \frac{3}{x ^{2}} d x

2 x e^{x} + e^{x} x^{2}

y = e^{- 7 x^{2}}

1 0^{x}

\int_{0}^{π} e^{- s t} sin (t) d t
