integral from 1 to 3 of (x+1)

Solution

\int_{1}^{3} (x + 1) d x

Solution

6

Solution steps

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

\int_{1}^{3} x d x = 4

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

= 4 + 2

Simplify

= 6
