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

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

\frac{e ^{2} - 1}{3}

Decimal Notation

2.12968 \dots

Solution steps

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

Apply u-substitution

: \int_{0}^{2} \frac{e ^{u}}{3} d u

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

Use the common integral:

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

= \frac{1}{3} [e^{u}]_{0}^{2}

Compute the boundaries:

e^{2} - 1

= \frac{1}{3} (e^{2} - 1)

Simplify

= \frac{e ^{2} - 1}{3}

\frac{d}{d x} (e^{4 x^{2}} \cdot 8 x)

f (x) = x^{3} - 15 x

\frac{d P}{d t} = Pt

\frac{d}{d x} (3 cos (5 x))
