integral from 1 to e of sqrt(ln(x))

\int_{1}^{e} ln (x) d x

e - \frac{π}{2} erfi (ln (e))

Solution steps

\int_{1}^{e} ln (x) d x

Apply Integration By Parts

: [x ln (x) - \int \frac{1}{2 ln ( x )} d x]_{1}^{e}

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

\int \frac{1}{2 ln ( x )} d x = \frac{π}{2} erfi (ln (x))

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

Simplify

[x ln (x) - \frac{π}{2} erfi (ln (x))]_{1}^{e} : [\frac{1}{2} (2 x ln (x) - π erfi (ln (x)))]_{1}^{e}

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

Compute the boundaries:

e - \frac{π}{2} erfi (ln (e))

= e - \frac{π}{2} erfi (ln (e))

n = 1 \sum \infty \frac{1}{n ^{n}}

\int sec^{2} (2 x t a) n^{5} 2 x d x

\int \frac{x}{3 - x} d x

\frac{e ^{x}}{3 + e ^{x}}

(p \cdot m - p^{2})^{- 1} \cdot d p = k \cdot d t
