integral from-10 to-6 of 1/(x+2)

\int_{- 10}^{- 6} \frac{1}{x + 2} d x

- ln (2)

Decimal

- 0.69314 \dots

Solution steps

\int_{- 10}^{- 6} \frac{1}{x + 2} d x

Apply u-substitution

= \int_{- 8}^{- 4} \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= [ln ∣ u ∣]_{- 8}^{- 4}

Compute the boundaries:

- ln (2)

= - ln (2)
