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

Solution

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

Solution

\frac{10}{3}

+1

Decimal Notation

3.33333 \dots

Solution steps

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

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

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

= 4 - \frac{2}{3}

Simplify

4 - \frac{2}{3} : \frac{10}{3}

= \frac{10}{3}
