integral from 2 to 3 of 1/(x+1)

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

2 ln (2) - ln (3)

Decimal Notation

0.28768 \dots

Solution steps

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

Apply u-substitution

: \int_{3}^{4} \frac{1}{u} d u

= \int_{3}^{4} \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= [ln ∣ u ∣]_{3}^{4}

Compute the boundaries:

2 ln (2) - ln (3)

= 2 ln (2) - ln (3)

\int_{0}^{1} e^{e^{x}} e^{x} d x

\int_{0}^{\frac{π}{6}} 2 cos (3 x) d x

\int_{y}^{2} sin (\frac{π x}{2 y}) d x

\int_{1}^{2} 3 x^{5} d x

\int_{1}^{3} (arctan (x)) d x
