integral from 1 to e of x

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

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

Decimal

3.19452 \dots

Solution steps

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

Apply the Power Rule

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

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

Compute the boundaries:

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

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

Simplify

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

\int_{- 2}^{2} (- 2 x^{2} + 8) d x

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

\int_{0}^{1} \frac{x}{1 + x ^{3}} d x

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

\int_{1}^{4} \frac{x - 1}{x} d x
