integral from 1 to 7 of ln(x)

\int_{1}^{7} ln (x) d x

7 ln (7) - 6

Decimal Notation

7.62137 \dots

Solution steps

\int_{1}^{7} ln (x) d x

Apply Integration By Parts

: [x ln (x) - \int 1 d x]_{1}^{7}

= [x ln (x) - \int 1 d x]_{1}^{7}

\int 1 d x = x

= [x ln (x) - x]_{1}^{7}

Compute the boundaries:

7 ln (7) - 6

= 7 ln (7) - 6

\int_{0}^{π} \frac{1}{cos ( x )} d x

\int_{x - 1}^{1 - x} 30 x y^{2} d y

\int_{0}^{1} 4 - 4 t^{3} d t

\int_{x}^{\infty} y e^{- y} d y

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