integral from 0 to 2 of (x-3x^2)^3

\int_{0}^{2} (x - 3 x^{2})^{3} d x

- \frac{9076}{35}

Decimal Notation

- 259.31428 \dots

Solution steps

\int_{0}^{2} (x - 3 x^{2})^{3} d x

Expand

(x - 3 x^{2})^{3} : x^{3} - 9 x^{4} + 27 x^{5} - 27 x^{6}

= \int_{0}^{2} x^{3} - 9 x^{4} + 27 x^{5} - 27 x^{6} 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_{0}^{2} x^{3} d x - \int_{0}^{2} 9 x^{4} d x + \int_{0}^{2} 27 x^{5} d x - \int_{0}^{2} 27 x^{6} d x

\int_{0}^{2} x^{3} d x = 4

\int_{0}^{2} 9 x^{4} d x = \frac{288}{5}

\int_{0}^{2} 27 x^{5} d x = 288

\int_{0}^{2} 27 x^{6} d x = \frac{3456}{7}

= 4 - \frac{288}{5} + 288 - \frac{3456}{7}

Simplify

4 - \frac{288}{5} + 288 - \frac{3456}{7} : - \frac{9076}{35}

= - \frac{9076}{35}

\int_{0}^{3 π} x sin (x) d x

\int_{1}^{4} x e^{x} d x

\int_{0}^{9} (81 - x^{2}) d x

\int_{- 1}^{0} (x + 4) cos (nπ x) d x

\int_{0}^{2} x^{2} x^{3} + 5 d x
