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

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

- \frac{8}{3}

Decimal

- 2.66666 \dots

Solution steps

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

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

\int_{- 2}^{0} x^{2} d x = \frac{8}{3}

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

= - 4 - \frac{8}{3} - (- 4)

Simplify

= - \frac{8}{3}

\int_{0}^{π} 4 sin (x) - 3 cos (x) d x

\int_{0}^{3} \frac{1}{x ^{2} - 2 x + 1} d x

\int_{- 1}^{0} \frac{5 - 3 x}{4 x - 3} d x

\int_{- 2}^{1} (- 2 x^{2} - 1) d x

\int_{- 1}^{1} (x + ∣ x - 1 ∣) d x
