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

Solution

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

Solution

\frac{14}{3}

+1

Decimal

4.66666 \dots

Solution steps

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

\int_{0}^{2} x^{2} d x = \frac{8}{3}

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

= \frac{8}{3} + 2

Simplify

\frac{8}{3} + 2 : \frac{14}{3}

= \frac{14}{3}
