integral from-1 to 3 of x^2e^{x^3+1}

\int_{- 1}^{3} x^{2} e^{x^{3} + 1} d x

\frac{e ^{28} - 1}{3}

Decimal Notation

482085688096.8243

Solution steps

\int_{- 1}^{3} x^{2} e^{x^{3} + 1} d x

Apply u-substitution

: \int_{0}^{28} \frac{e ^{u}}{3} d u

= \int_{0}^{28} \frac{e ^{u}}{3} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int_{0}^{28} e^{u} d u

Use the common integral:

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

= \frac{1}{3} [e^{u}]_{0}^{28}

Compute the boundaries:

e^{28} - 1

= \frac{1}{3} (e^{28} - 1)

Simplify

= \frac{e ^{28} - 1}{3}

\int cot (14 x) d x

\int sec^{2} (2 y) d y

\frac{d}{d x} (4 (x + 2)^{\frac{3}{2}})

\frac{d y}{d t} = - \frac{y}{t} - 6

\int \frac{( e ^{x} )}{e ^{2 x} + 1} d x
