integral of (x+1)/((x-1)^2)

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

ln ∣ x - 1 ∣ - \frac{2}{x - 1} + C

Solution steps

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

Expand

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

Apply the Sum Rule:

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

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

\int \frac{x}{( x - 1 ) ^{2}} d x = ln ∣ x - 1 ∣ - \frac{1}{x - 1}

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

= ln ∣ x - 1 ∣ - \frac{1}{x - 1} - \frac{1}{x - 1}

Simplify

ln ∣ x - 1 ∣ - \frac{1}{x - 1} - \frac{1}{x - 1} : ln ∣ x - 1 ∣ - \frac{2}{x - 1}

= ln ∣ x - 1 ∣ - \frac{2}{x - 1}

Add a constant to the solution

= ln ∣ x - 1 ∣ - \frac{2}{x - 1} + C

\int x^{2} + 6 x d x

\frac{\partial}{\partial x} (- \frac{v ( x , t )}{b ( x , t ) x - b ( x , t ) v ( x , t ) t})

\int π sin (x) d x

x \to 6 + lim (x - 6)

\frac{d}{d x} (\frac{x ^{2}}{x})
