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

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

\frac{e ^{2}}{3} - 1

Decimal Notation

1.46301 \dots

Solution steps

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

Apply Integration By Parts

: [- \frac{e ^{x} x}{1 + x} - \int - e^{x} d x]_{0}^{2}

= [- \frac{e ^{x} x}{1 + x} - \int - e^{x} d x]_{0}^{2}

\int - e^{x} d x = - e^{x}

= [- \frac{e ^{x} x}{1 + x} - (- e^{x})]_{0}^{2}

Simplify

[- \frac{e ^{x} x}{1 + x} - (- e^{x})]_{0}^{2} : [\frac{e ^{x}}{1 + x}]_{0}^{2}

= [\frac{e ^{x}}{1 + x}]_{0}^{2}

Compute the boundaries:

\frac{e ^{2}}{3} - 1

= \frac{e ^{2}}{3} - 1

\int_{1}^{5} x^{2} - 4 x - 12 d x

\int_{0}^{2} \frac{1}{t - 2} d t

\int_{2}^{8} x^{2} + x + 1 + \frac{1}{x} d x

\int_{0}^{5} (- 3 x - 5 x^{2}) d x

\int_{3}^{7} e^{x} - 3 x d x
