integral of 1/(sqrt(x)\sqrt{1+x)}

\int \frac{1}{x 1 + x} d x

2 ln x + 1 + x + C

Solution steps

\int \frac{1}{x 1 + x} d x

Apply u-substitution

: \int \frac{2}{1 + u ^{2}} d u

= \int \frac{2}{1 + u ^{2}} d u

Take the constant out:

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

= 2 \cdot \int \frac{1}{1 + u ^{2}} d u

Use the common integral:

\int \frac{1}{1 + u ^{2}} d u = ln u^{2} + 1 + u

= 2 ln u^{2} + 1 + u

Substitute back

u = x

= 2 ln (x)^{2} + 1 + x

(x)^{2} = x

= 2 ln x + 1 + x

Add a constant to the solution

= 2 ln x + 1 + x + C

\int e^{3 x + 9} d x

\frac{d}{d x} (e^{- 2 x^{3} + 2})

\frac{\partial}{\partial y} (e^{x} cos (x + y))

\frac{\partial}{\partial x} (\frac{2}{3} (1 - x)^{\frac{3}{2}})

n = 0 \sum \infty (\frac{1}{9})^{n}
