integral from 0 to 1 of x^{-1}ln(x)

\int_{0}^{1} x^{- 1} ln (x) d x

diverges

Solution steps

\int_{0}^{1} x^{- 1} ln (x) d x

Simplify

x^{- 1} ln (x) : \frac{ln ( x )}{x}

= \int_{0}^{1} \frac{ln ( x )}{x} d x

Apply Integration By Parts

= [ln (x) - \int \frac{1 - ln ( x )}{x} d x]_{0}^{1}

\int \frac{1 - ln ( x )}{x} d x = - \frac{( 1 - ln ( x ) ) ^{2}}{2}

= [ln (x) - (- \frac{( 1 - ln ( x ) ) ^{2}}{2})]_{0}^{1}

Simplify

[ln (x) - (- \frac{( 1 - ln ( x ) ) ^{2}}{2})]_{0}^{1} : [\frac{1}{2} (ln^{2} (x) + 1)]_{0}^{1}

= [\frac{1}{2} (ln^{2} (x) + 1)]_{0}^{1}
