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

Solution

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

Solution

- \frac{3}{4}

+1

Decimal

- 0.75

Solution steps

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

\int_{- 2}^{1} x^{3} d x = - \frac{15}{4}

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

= - \frac{15}{4} + 3

Simplify

- \frac{15}{4} + 3 : - \frac{3}{4}

= - \frac{3}{4}
