integral from 0 to 5 of (x/(sqrt(x+4)))

\int_{0}^{5} (\frac{x}{x + 4}) d x

\frac{14}{3}

Decimal Notation

4.66666 \dots

Solution steps

\int_{0}^{5} \frac{x}{x + 4} d x

Apply u-substitution

: \int_{2}^{3} 2 (u^{2} - 4) d u

= \int_{2}^{3} 2 (u^{2} - 4) d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{2}^{3} u^{2} - 4 d u

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 2 (\int_{2}^{3} u^{2} d u - \int_{2}^{3} 4 d u)

\int_{2}^{3} u^{2} d u = \frac{19}{3}

\int_{2}^{3} 4 d u = 4

= 2 (\frac{19}{3} - 4)

Simplify

2 (\frac{19}{3} - 4) : \frac{14}{3}

= \frac{14}{3}

y^{^{'}} + y + 1 = 0

\frac{d}{d x} ((1 + x) cos (x))

f (t) = cos^{2} (e^{c o s^{2} (t)})

\int \frac{19}{x ^{2} + 1} d x

\frac{\partial}{\partial x} (7 e^{x})
