integral from-1 to 2 of (x^2-1)

Solution

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

Solution

0

Solution steps

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

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

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

= 3 - 3

Simplify

= 0
