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

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

\frac{e ^{8} - 1}{4}

Decimal

744.98949 \dots

Solution steps

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

Apply u-substitution

: \int_{0}^{8} \frac{e ^{u}}{4} d u

= \int_{0}^{8} \frac{e ^{u}}{4} d u

Take the constant out:

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

= \frac{1}{4} \cdot \int_{0}^{8} e^{u} d u

Use the common integral:

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

= \frac{1}{4} [e^{u}]_{0}^{8}

Compute the boundaries:

e^{8} - 1

= \frac{1}{4} (e^{8} - 1)

Simplify

= \frac{e ^{8} - 1}{4}

\int_{- 1}^{1} (3 t - 8) d t

\int_{- 2}^{2} 4 x^{2} + 1 d x

\int_{1}^{4} x (1 + x) d x

\int_{0}^{\frac{3}{4}} \frac{1}{16 x ^{2} + 9} d x

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