integral from 1 to e^2 of ((ln(x))^2)/x

\int_{1}^{e^{2}} \frac{( ln ( x ) ) ^{2}}{x} d x

\frac{8}{3}

Decimal Notation

2.66666 \dots

Solution steps

\int_{1}^{e^{2}} \frac{( ln ( x ) ) ^{2}}{x} d x

Apply u-substitution

: \int_{0}^{2} u^{2} d u

= \int_{0}^{2} u^{2} d u

Apply the Power Rule

: [\frac{u ^{3}}{3}]_{0}^{2}

= [\frac{u ^{3}}{3}]_{0}^{2}

Compute the boundaries:

\frac{8}{3}

= \frac{8}{3}

\int_{0}^{1} sin (π) x d x

\int_{0}^{9} x^{2} - 1 d x

\int_{1}^{x} tan (t) d t

\int_{- 1}^{2} (x^{3} + 5 x^{2} - 1) d x

\int_{0}^{x} 8 x y d y
