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

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

\frac{x ^{3}}{3} + \frac{x ^{2}}{2} + x + C

Solution steps

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

Simplify

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

= \int x^{2} + x + 1 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^{2} d x + \int x d x + \int 1 d x

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

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

\int 1 d x = x

= \frac{x ^{3}}{3} + \frac{x ^{2}}{2} + x

Add a constant to the solution

= \frac{x ^{3}}{3} + \frac{x ^{2}}{2} + x + C

\int sec (x) tan (x) 3 + sec (x) d x

\int x (x^{2} + 3 x - 8) d x

\int \frac{1}{x ^{8} + x} d x

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

\int \frac{20 ( 1 - x ^{2} )}{x ^{2} + 1} d x
