integral from 0 to 2 of 9-x^2

Solution

\int_{0}^{2} 9 - x^{2} d x

Solution

\frac{46}{3}

+1

Decimal

15.33333 \dots

Solution steps

\int_{0}^{2} 9 - 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_{0}^{2} 9 d x - \int_{0}^{2} x^{2} d x

\int_{0}^{2} 9 d x = 18

\int_{0}^{2} x^{2} d x = \frac{8}{3}

= 18 - \frac{8}{3}

Simplify

18 - \frac{8}{3} : \frac{46}{3}

= \frac{46}{3}
