integral of 1/(sqrt(x)(1+\sqrt{x))^3}

\int \frac{1}{x ( 1 + x ) ^{3}} d x

- \frac{1}{( 1 + x ) ^{2}} + C

Solution steps

\int \frac{1}{x ( 1 + x ) ^{3}} d x

Apply u-substitution

: \int \frac{2}{u ^{3}} d u

= \int \frac{2}{u ^{3}} 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}{u ^{3}} d u

Apply the Power Rule

: - \frac{1}{2 u ^{2}}

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

Substitute back

u = 1 + x

= 2 (- \frac{1}{2 ( 1 + x ) ^{2}})

Simplify

2 (- \frac{1}{2 ( 1 + x ) ^{2}}) : - \frac{1}{( 1 + x ) ^{2}}

= - \frac{1}{( 1 + x ) ^{2}}

Add a constant to the solution

= - \frac{1}{( 1 + x ) ^{2}} + C

x \to 2 lim (a x^{2} - 2 b x + 1)

\int \frac{e ^{x} - e ^{- x}}{e ^{x} + e ^{- x}} d x

\frac{\partial}{\partial x} (sin^{2} (k x))

y^{^{'}} - \frac{9}{x} y = \frac{( y ^{5} )}{x ^{8}}

y = sin (5 x)
