integral of (x^2+4)/(x(x-1)^2)

\int \frac{x ^{2} + 4}{x ( x - 1 ) ^{2}} d x

- 3 ln ∣ x - 1 ∣ - \frac{5}{x - 1} + 4 ln ∣ x ∣ + C

Solution steps

\int \frac{x ^{2} + 4}{x ( x - 1 ) ^{2}} d x

Expand

\frac{x ^{2} + 4}{x ( x - 1 ) ^{2}} : \frac{x ^{2}}{x ( x - 1 ) ^{2}} + \frac{4}{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{x ^{2}}{x ( x - 1 ) ^{2}} d x + \int \frac{4}{x ( x - 1 ) ^{2}} d x

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

\int \frac{4}{x ( x - 1 ) ^{2}} d x = 4 (ln ∣ x ∣ - ln ∣ x - 1 ∣ - \frac{1}{x - 1})

= ln ∣ x - 1 ∣ - \frac{1}{x - 1} + 4 (ln ∣ x ∣ - ln ∣ x - 1 ∣ - \frac{1}{x - 1})

Simplify

ln ∣ x - 1 ∣ - \frac{1}{x - 1} + 4 (ln ∣ x ∣ - ln ∣ x - 1 ∣ - \frac{1}{x - 1}) : - 3 ln ∣ x - 1 ∣ - \frac{5}{x - 1} + 4 ln ∣ x ∣

= - 3 ln ∣ x - 1 ∣ - \frac{5}{x - 1} + 4 ln ∣ x ∣

Add a constant to the solution

= - 3 ln ∣ x - 1 ∣ - \frac{5}{x - 1} + 4 ln ∣ x ∣ + C

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

\int x ln (3 x^{3}) d x

\int 4 sec^{2} (8 x + 3) d x

\int 7 tan (x) sec^{5} (x) d x

\int \frac{sin ( 3 θ )}{8 + cos ^{2} ( 3 θ )} d θ
