integral from 0 to 4 of sqrt(x)-x/2

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

\frac{4}{3}

Decimal

1.33333 \dots

Solution steps

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

\int_{0}^{4} x d x = \frac{16}{3}

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

= \frac{16}{3} - 4

Simplify

\frac{16}{3} - 4 : \frac{4}{3}

= \frac{4}{3}
