integral from 0 to 16 of sqrt(x)-3

\int_{0}^{16} x - 3 d x

- \frac{16}{3}

Decimal

- 5.33333 \dots

Solution steps

\int_{0}^{16} x - 3 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}^{16} x d x - \int_{0}^{16} 3 d x

\int_{0}^{16} x d x = \frac{128}{3}

\int_{0}^{16} 3 d x = 48

= \frac{128}{3} - 48

Simplify

\frac{128}{3} - 48 : - \frac{16}{3}

= - \frac{16}{3}

\int_{1}^{3} (x^{2} - 6 x + 5) d x

\int_{2}^{4} 3 x - 1 + 2 x^{2} d x

\int_{0}^{2} 5 - t^{3} d t

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

\int_{0}^{y} x e^{- y} d x
