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

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

- \frac{1}{x - 1} - ln ∣ x - 1 ∣ + C

Solution steps

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

Expand

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

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

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

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

Simplify

= - \frac{1}{x - 1} - ln ∣ x - 1 ∣

Add a constant to the solution

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

\int - 3 x^{2} 2^{4 x} d x

\int \frac{1 + x}{( x ^{2} - 2 x - 3 ) ^{3}} d x

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

\int 4 x sin^{2} (x) d x

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