integral from 2 to 3 of (x^3+x)

Solution

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

Solution

\frac{75}{4}

+1

Decimal

18.75

Solution steps

\int_{2}^{3} x^{3} + x d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{2}^{3} x^{3} d x + \int_{2}^{3} x d x

\int_{2}^{3} x^{3} d x = \frac{65}{4}

\int_{2}^{3} x d x = \frac{5}{2}

= \frac{65}{4} + \frac{5}{2}

Simplify

\frac{65}{4} + \frac{5}{2} : \frac{75}{4}

= \frac{75}{4}
