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

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

- 2 ln (2) + \frac{3}{2}

Decimal Notation

0.11370 \dots

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int_{0}^{1} 2 d x = 2

\int_{0}^{1} x d x = \frac{1}{2}

\int_{0}^{1} \frac{2}{x + 1} d x = 2 ln (2)

= 2 - \frac{1}{2} - 2 ln (2)

Combine the fractions

2 - \frac{1}{2} : \frac{3}{2}

= - 2 ln (2) + \frac{3}{2}

\int_{0}^{4} x^{3} - x^{2} + 1 d x

\int_{1}^{4} - x^{2} + 8 x d x

\int_{0}^{π} 2 e^{x} sin (x) d x

\int_{e^{3}}^{e^{5}} \frac{1}{x ln ( x )} d x

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