integral from 0 to 1 of (1/(1+x))

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

ln (2)

Decimal Notation

0.69314 \dots

Solution steps

\int_{0}^{1} \frac{1}{1 + x} d x

Apply u-substitution

: \int_{1}^{2} \frac{1}{u} d u

= \int_{1}^{2} \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= [ln ∣ u ∣]_{1}^{2}

Compute the boundaries:

ln (2)

= ln (2)

\int_{0}^{1} \frac{32}{x ^{2} - 16} d x

\int_{1}^{2} \frac{x + 2}{x + 3} d x

\int_{- 7}^{6} - 2 y^{3} - y^{2} + 36 d y

\int_{0}^{1} 1 - x^{2} + \frac{x ^{4}}{2} d x

\int_{0}^{\frac{π}{6}} cos^{8} (3 A) d A
