integral from 0 to 1 of e^{2x+1}

\int_{0}^{1} e^{2 x + 1} d x

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

Decimal Notation

8.68362 \dots

Solution steps

\int_{0}^{1} e^{2 x + 1} d x

Apply u-substitution

: \int_{1}^{3} e^{u} \frac{1}{2} d u

= \int_{1}^{3} e^{u} \frac{1}{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_{1}^{3} e^{u} d u

Use the common integral:

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

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

Compute the boundaries:

e^{3} - e

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

Simplify

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

\int_{0}^{3} x 3 - x d x

\int_{0}^{3} x^{2} (1 - x) d x

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

\int_{0}^{11} 5 + 0.25 x^{2} d x

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