integral from 0 to 3 of x+2

Solution

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

Solution

\frac{21}{2}

+1

Decimal

10.5

Solution steps

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

\int_{0}^{3} x d x = \frac{9}{2}

\int_{0}^{3} 2 d x = 6

= \frac{9}{2} + 6

Simplify

\frac{9}{2} + 6 : \frac{21}{2}

= \frac{21}{2}
