integral from 0 to 1 of 1/(1+sqrt(x))

\int_{0}^{1} \frac{1}{1 + x} d x

2 (1 - ln (2))

Decimal

0.61370 \dots

Solution steps

\int_{0}^{1} \frac{1}{1 + x} d x

Apply u-substitution

: \int_{1}^{2} \frac{2 ( u - 1 )}{u} d u

= \int_{1}^{2} \frac{2 ( u - 1 )}{u} d u

Take the constant out:

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

= 2 \cdot \int_{1}^{2} \frac{u - 1}{u} d u

Expand

\frac{u - 1}{u} : 1 - \frac{1}{u}

= 2 \cdot \int_{1}^{2} 1 - \frac{1}{u} 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_{1}^{2} 1 d u - \int_{1}^{2} \frac{1}{u} d u)

\int_{1}^{2} 1 d u = 1

\int_{1}^{2} \frac{1}{u} d u = ln (2)

= 2 (1 - ln (2))

n = 1 \sum \infty \frac{n}{2 n ^{4} + 2}

\int_{0}^{1} e^{3 x} d x

(2, 3), (4, 5)

f (x) = 4 x + 32

\frac{d}{d j} (i + j)
