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

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

\frac{3 x ^{4}}{4} - \frac{x ^{3}}{3} + \frac{x ^{2}}{2} - x + C

Solution steps

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

\int 3 x^{3} d x = \frac{3 x ^{4}}{4}

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

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

\int 1 d x = x

= \frac{3 x ^{4}}{4} - \frac{x ^{3}}{3} + \frac{x ^{2}}{2} - x

Add a constant to the solution

= \frac{3 x ^{4}}{4} - \frac{x ^{3}}{3} + \frac{x ^{2}}{2} - x + C

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

\int 6 x - 6 d x

\int (4 - 3 x)^{8} d x

\int e^{c o s (23 t)} sin (23 t) d t

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