integral from 0 to 2 of x/(sqrt(x+2))

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

2 (\frac{8 - 2 2}{3} - 4 + 22)

Decimal Notation

1.10456 \dots

Solution steps

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

Apply u-substitution

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

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

Take the constant out:

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

= 2 \cdot \int_{2}^{2} u^{2} - 2 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}^{2} u^{2} d u - \int_{2}^{2} 2 d u)

\int_{2}^{2} u^{2} d u = \frac{8 - 2 2}{3}

\int_{2}^{2} 2 d u = 4 - 22

= 2 (\frac{8 - 2 2}{3} - (4 - 22))

Simplify

= 2 (\frac{8 - 2 2}{3} - 4 + 22)

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

\int_{0}^{\frac{1}{2}} \frac{x}{1 - x} d x

\int_{1}^{4} (2 - x) - x d x

\int_{1}^{2.2} x^{3} \cdot e^{x + 1} d x

\int_{0}^{2} \frac{2 x - 1}{( x + 3 ) ^{2}} d x
