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

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

2 ln ∣ x ∣ - \frac{1}{x} - 2 ln ∣ x - 1 ∣ - \frac{1}{x - 1} + C

Solution steps

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

Take the partial fraction of

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

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

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

\int \frac{2}{x} d x = 2 ln ∣ x ∣

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

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

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

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

Add a constant to the solution

= 2 ln ∣ x ∣ - \frac{1}{x} - 2 ln ∣ x - 1 ∣ - \frac{1}{x - 1} + C

\frac{d}{d x} (3 x^{5} - 30 x^{3})

f (x) = 5 x^{2} - 3 x + 7

\frac{\partial}{\partial x} (\frac{x ^{3}}{3} + 4 y)

\frac{d y}{d x} = x^{6} y^{- 7}

1 - y^{2}
