integral from 1 to 2 of-x+2

Solution

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

Solution

\frac{1}{2}

+1

Decimal Notation

0.5

Solution steps

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

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

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

= - \frac{3}{2} + 2

Simplify

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

= \frac{1}{2}
