integral of (sqrt(x)-1/x)

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

\frac{2}{3} x^{\frac{3}{2}} - ln ∣ x ∣ + C

Solution steps

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

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

\int \frac{1}{x} d x = ln ∣ x ∣

= \frac{2}{3} x^{\frac{3}{2}} - ln ∣ x ∣

Add a constant to the solution

= \frac{2}{3} x^{\frac{3}{2}} - ln ∣ x ∣ + C

\int (7 x^{\frac{2}{5}} + 8 x^{- \frac{4}{5}}) d x

\int \frac{y ^{2} + 5}{y ^{2} + 9} d y

\int \frac{3 x sin ^{2} ( x )}{cos ^{4} ( x )} d x

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