limit as x approaches 1+of (1-x)/(|1-x|)

解

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

解

- 1

解答ステップ

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

1 - x

は

x \to 1 +

の場合, 負になる。従って

∣ 1 - x ∣ = - 1 + x

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

\frac{1 - x}{- 1 + x} = - 1

= x \to 1 + lim (- 1)

x \to a lim c = c

= - 1
