integral from 0 to 2 of xsqrt(1+x^2)

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

\frac{5 5 - 1}{3}

Decimal Notation

3.39344 \dots

Solution steps

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

Apply u-substitution

: \int_{1}^{5} u^{2} d u

= \int_{1}^{5} u^{2} d u

Apply the Power Rule

: [\frac{u ^{3}}{3}]_{1}^{5}

= [\frac{u ^{3}}{3}]_{1}^{5}

Compute the boundaries:

\frac{5 5}{3} - \frac{1}{3}

= \frac{5 5}{3} - \frac{1}{3}

Simplify

= \frac{5 5 - 1}{3}

\int_{1}^{2} \frac{15 x}{5 x ^{2} + 6} d x

\int_{0}^{4} 1 + 64 x^{2} d x

\int_{8}^{\infty} ln (x) d x

\int_{- 5}^{0} 4 - x d x

\int_{0}^{3} 2 x + 4 x^{2} + 16 x^{3} d x
