integral of (1/x+3/(x^2))

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

ln ∣ x ∣ - \frac{3}{x} + C

Solution steps

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

\int \frac{1}{x} d x = ln ∣ x ∣

\int \frac{3}{x ^{2}} d x = - \frac{3}{x}

= ln ∣ x ∣ - \frac{3}{x}

Add a constant to the solution

= ln ∣ x ∣ - \frac{3}{x} + C

\int sin (4 x - 1) d x

\int (2 x - 3) (5 x^{2} - 1) d x

\int (2 x y^{3} + y^{6}) d x

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

\int x^{2} \cdot e^{(x^{3})} d x
