integral from-1 to 1 of e^x*x

\int_{- 1}^{1} e^{x} \cdot x d x

\frac{2}{e}

Decimal Notation

0.73575 \dots

Solution steps

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

Apply Integration By Parts

: [e^{x} x - \int e^{x} d x]_{- 1}^{1}

= [e^{x} x - \int e^{x} d x]_{- 1}^{1}

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

= [e^{x} x - e^{x}]_{- 1}^{1}

Compute the boundaries:

\frac{2}{e}

= \frac{2}{e}

\int_{0}^{1} (3 x - 3 x^{2}) d x

\int_{0}^{π} (π^{2} - x^{2}) d x

\int_{- π}^{π} cos (2 x) cos (2 x) d x

\int_{1}^{2} (4 - 3 x)^{2} d x

\int_{1}^{e^{2}} \frac{10 ln ( x )}{x} d x
