limit as x approaches 1+of (x-1)ln(x-1)

x \to 1 + lim ((x - 1) ln (x - 1))

0

Solution steps

x \to 1 + lim ((x - 1) ln (x - 1))

Rewrite for L'Hopital

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

Apply L'Hopital's Rule

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

Simplify

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

= x \to 1 + lim (1 - x)

Plug in the value

x = 1

= 1 - 1

Simplify

= 0
