integral from 4 to 16 of 2sqrt(x)-1

\int_{4}^{16} 2 x - 1 d x

\frac{188}{3}

Decimal Notation

62.66666 \dots

Solution steps

\int_{4}^{16} 2 x - 1 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}^{16} 2 x d x - \int_{4}^{16} 1 d x

\int_{4}^{16} 2 x d x = \frac{224}{3}

\int_{4}^{16} 1 d x = 12

= \frac{224}{3} - 12

Simplify

\frac{224}{3} - 12 : \frac{188}{3}

= \frac{188}{3}

\int_{0}^{x} x^{3} y^{2} d y

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

\int_{\frac{1}{4}}^{\frac{1}{2}} \frac{2}{5} (x + 2) d x

\int_{2}^{4} 3 x ln (x) d x

\int_{y}^{8 - y^{2}} 1 d x
