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

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

ln (2)

Decimal Notation

0.69314 \dots

Solution steps

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

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_{- 3}^{2} x^{3} d x

\int_{2}^{5} \frac{1}{x - 1} d x

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

\int_{0}^{\frac{π}{2}} cos (x) \frac{1}{2} d x

\int_{0}^{2} y 4 - y^{2} d y
