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

Solution

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

Solution

0

Solution steps

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

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

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

= 3 - 3

Simplify

= 0
