integral from 0 to 4 of e^xx^2

\int_{0}^{4} e^{x} x^{2} d x

10 e^{4} - 2

Decimal

543.98150 \dots

Solution steps

\int_{0}^{4} e^{x} x^{2} d x

Apply Integration By Parts

: [x^{2} e^{x} - \int 2 x e^{x} d x]_{0}^{4}

= [x^{2} e^{x} - \int 2 x e^{x} d x]_{0}^{4}

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

= [x^{2} e^{x} - 2 (e^{x} x - e^{x})]_{0}^{4}

Compute the boundaries:

10 e^{4} - 2

= 10 e^{4} - 2

\int_{0}^{2} \frac{4}{5 x + 1} d x

\int_{- 3}^{1} e^{u + 3} d u

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

\int_{0}^{x^{2}} sin (x) d x

\int_{0}^{π} cos (x + y + z) d x
