integral from 0 to 2 of xe^{x^2}

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

\frac{e ^{4} - 1}{2}

Decimal

26.79907 \dots

Solution steps

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

Apply u-substitution

: \int_{0}^{4} \frac{e ^{u}}{2} d u

= \int_{0}^{4} \frac{e ^{u}}{2} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int_{0}^{4} e^{u} d u

Use the common integral:

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

= \frac{1}{2} [e^{u}]_{0}^{4}

Compute the boundaries:

e^{4} - 1

= \frac{1}{2} (e^{4} - 1)

Simplify

= \frac{e ^{4} - 1}{2}

\int \frac{3 x ^{2} - 7}{x ^{3}} d x

y = x + 2, y = - 1, x = 2, x = 5

9 z - 8

\int x^{4} + 4 x^{2} d x

\int \frac{x - 7}{x ^{2} - x - 12} d x
