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

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

- \frac{1}{x} - ln ∣ x ∣ + C

Solution steps

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

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

\int \frac{1}{x} d x = ln ∣ x ∣

= - \frac{1}{x} - ln ∣ x ∣

Add a constant to the solution

= - \frac{1}{x} - ln ∣ x ∣ + C

\int 4 cos (x) sin (x) d x

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

\int (e^{x} + 2^{x})^{2} d x

\int (3 - x) x d x

\int \frac{1}{4 x - x ^{2} - 3} d x
