integral from 1 to 2 of x+1

Solution

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

Solution

\frac{5}{2}

+1

Decimal Notation

2.5

Solution steps

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

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

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

= \frac{3}{2} + 1

Simplify

\frac{3}{2} + 1 : \frac{5}{2}

= \frac{5}{2}
