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

解

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

0

解答ステップ

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

x \to a lim [\frac{f ( x )}{g ( x )}] = \frac{lim _{x \to a} f ( x )}{lim _{x \to a} g ( x )}, x \to a lim g (x) \neq = 0

不定形式の場合を除く

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

x \to 0 + lim (1) = 1

x \to 0 + lim (1 + ln (x)) = - \infty

= \frac{1}{- \infty}

無限大の特性を適用する:

\frac{c}{- \infty} = 0

= 0
