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

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

\frac{x ^{5}}{5} - x^{2} - \frac{1}{x} + C

Solution steps

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

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

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

Expand

\frac{( x ^{3} - 1 ) ^{2}}{x ^{2}} : x^{4} - 2 x + \frac{1}{x ^{2}}

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

\int x^{4} d x = \frac{x ^{5}}{5}

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

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

= \frac{x ^{5}}{5} - x^{2} - \frac{1}{x}

Add a constant to the solution

= \frac{x ^{5}}{5} - x^{2} - \frac{1}{x} + C

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

\int \frac{5 x - 3}{x ^{2} + 5 x + 4} d x

\int cos (π) θ d θ

\int \frac{162}{x ^{3}} + 2 x d x

\int (1 - t) (8 + t^{2}) d t
