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

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

- \frac{1}{2 x ^{2}} - ln ∣ x ∣ + C

Solution steps

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

Expand

\frac{1 - x ^{2}}{x ^{3}} : \frac{1}{x ^{3}} - \frac{1}{x}

= \int \frac{1}{x ^{3}} - \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 ^{3}} d x - \int \frac{1}{x} d x

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

\int \frac{1}{x} d x = ln ∣ x ∣

= - \frac{1}{2 x ^{2}} - ln ∣ x ∣

Add a constant to the solution

= - \frac{1}{2 x ^{2}} - ln ∣ x ∣ + C

\int \frac{1 + sin ( x )}{1 - cos ( x )} d x

\int \frac{2 ^{x} 3 ^{x}}{9 ^{x} - 4 ^{x}} d x

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

\int sin ((x^{2})^{2}) d (x^{2})^{2}

\int 18 x - x^{2} d x
