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

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

2 ln ∣ x ∣ + \frac{1}{x} + C

Solution steps

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

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

= 2 ln ∣ x ∣ - (- \frac{1}{x})

Simplify

= 2 ln ∣ x ∣ + \frac{1}{x}

Add a constant to the solution

= 2 ln ∣ x ∣ + \frac{1}{x} + C

\int \frac{1}{x ^{2} + 10 x - 6} d x

\int tan^{4} (5 x) d x

x^{4} + 2 e^{x}

x \to 2 i lim (\frac{x ^{2}}{2})

\int 6 x sin (x) d x
