integral from 0 to 4 of x-x^2

Solution

\int_{0}^{4} x - x^{2} d x

Solution

- \frac{40}{3}

+1

Decimal

- 13.33333 \dots

Solution steps

\int_{0}^{4} x - 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_{0}^{4} x d x - \int_{0}^{4} x^{2} d x

\int_{0}^{4} x d x = 8

\int_{0}^{4} x^{2} d x = \frac{64}{3}

= 8 - \frac{64}{3}

Simplify

8 - \frac{64}{3} : - \frac{40}{3}

= - \frac{40}{3}
