integral from 1 to 2 of x+3

Solution

\int_{1}^{2} x + 3 d x

Solution

\frac{9}{2}

+1

Decimal

4.5

Solution steps

\int_{1}^{2} x + 3 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_{1}^{2} x d x + \int_{1}^{2} 3 d x

\int_{1}^{2} x d x = \frac{3}{2}

\int_{1}^{2} 3 d x = 3

= \frac{3}{2} + 3

Simplify

\frac{3}{2} + 3 : \frac{9}{2}

= \frac{9}{2}
