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

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

\frac{32}{3}

Decimal

10.66666 \dots

Solution steps

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

\int_{0}^{4} 2 x d x = \frac{32}{3}

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

= \frac{32}{3} - 0

Simplify

= \frac{32}{3}

\int_{x}^{2} ln (t) d t

\int_{- 5}^{7} x d x

\int_{2}^{3} (x + 2) d x

\int_{0}^{3} (2 x + 3) d x

\int_{0}^{\frac{1}{8}} arccos (8 x) d x
