limit as x approaches infinity of 1/(sqrt(x))-1/(sqrt(x+1))

解

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

解

0

解答ステップ

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

x \to a lim [f (x) \pm g (x)] = x \to a lim f (x) \pm x \to a lim g (x)

不定形式の場合を除く

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

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

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

= 0 - 0
