integral from-4 to 5 of (1-x)

Solution

\int_{- 4}^{5} (1 - x) d x

Solution

\frac{9}{2}

+1

Decimal

4.5

Solution steps

\int_{- 4}^{5} 1 - x 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_{- 4}^{5} 1 d x - \int_{- 4}^{5} x d x

\int_{- 4}^{5} 1 d x = 9

\int_{- 4}^{5} x d x = \frac{9}{2}

= 9 - \frac{9}{2}

Simplify

9 - \frac{9}{2} : \frac{9}{2}

= \frac{9}{2}
