integral from 0 to 1 of x^2e^{x-1}

\int_{0}^{1} x^{2} e^{x - 1} d x

1 - \frac{2}{e}

Decimal

0.26424 \dots

Solution steps

\int_{0}^{1} x^{2} e^{x - 1} d x

Apply Integration By Parts

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

\int 2 x e^{x - 1} d x = 2 (e^{x - 1} x - e^{x - 1})

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

Compute the boundaries:

1 - \frac{2}{e}

= 1 - \frac{2}{e}
