integral from-1 to 0 of 2x+x^2-x^3

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

- \frac{5}{12}

Decimal

- 0.41666 \dots

Solution steps

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

\int_{- 1}^{0} 2 x d x = - 1

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

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

= - 1 + \frac{1}{3} - (- \frac{1}{4})

Simplify

- 1 + \frac{1}{3} - (- \frac{1}{4}) : - \frac{5}{12}

= - \frac{5}{12}

\int_{0}^{5} u^{2} + u + 1 d u

\int_{0}^{\infty} e^{- (x)} d x

\int_{0}^{5} t e^{- 0.3 t} d t

\int_{0}^{5} x - 1 d x

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