integral from-1 to 0 of 1/(2+x)

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

ln (2)

Decimal

0.69314 \dots

Solution steps

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

Apply u-substitution

= \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)
