integral from-2 to 3 of x^3-x^2-6x

\int_{- 2}^{3} x^{3} - x^{2} - 6 x d x

- \frac{125}{12}

Decimal

- 10.41666 \dots

Solution steps

\int_{- 2}^{3} x^{3} - x^{2} - 6 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_{- 2}^{3} x^{3} d x - \int_{- 2}^{3} x^{2} d x - \int_{- 2}^{3} 6 x d x

\int_{- 2}^{3} x^{3} d x = \frac{65}{4}

\int_{- 2}^{3} x^{2} d x = \frac{35}{3}

\int_{- 2}^{3} 6 x d x = 15

= \frac{65}{4} - \frac{35}{3} - 15

Simplify

\frac{65}{4} - \frac{35}{3} - 15 : - \frac{125}{12}

= - \frac{125}{12}

\int_{0}^{π} (8 sin (x)) d x

\int_{0}^{5} sin (x^{2}) d x

\int_{0}^{L} x^{2} cos (\frac{nπ x}{L}) d x

\int_{6}^{12} \frac{1}{x ^{2}} d x

\int_{1}^{2} 3 \cdot x^{2} \cdot (x^{3} + 3)^{6} d x
