integral from 0 to 1 of xe^{-1}

\int_{0}^{1} x e^{- 1} d x

\frac{1}{2 e}

Decimal

0.18393 \dots

Solution steps

\int_{0}^{1} x e^{- 1} d x

Take the constant out:

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

= e^{- 1} \cdot \int_{0}^{1} x d x

Apply exponent rule:

a^{- 1} = \frac{1}{a}

= \frac{1}{e} \cdot \int_{0}^{1} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{0}^{1}

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

Compute the boundaries:

\frac{1}{2}

= \frac{1}{e} \cdot \frac{1}{2}

Simplify

= \frac{1}{2 e}

\int_{1}^{4} (x^{4} + 5 x^{2}) d x

\int_{0}^{2} x^{3} (2 + x^{4})^{3} d x

\int_{0}^{2} 3 x^{3} - 2 x^{2} - e^{x} d x

\int_{0}^{\frac{π}{2}} (1 + sin (x)) d x

\int_{0}^{1} sin (t) d t
