integral from 0 to 9 of |x^2-1|

Solution

\int_{0}^{9} x^{2} - 1 d x

Solution

\frac{706}{3}

+1

Decimal Notation

235.33333 \dots

Solution steps

\int_{0}^{9} x^{2} - 1 d x

Eliminate Absolutes

= \int_{0}^{1} - x^{2} + 1 d x + \int_{1}^{9} x^{2} - 1 d x

\int_{0}^{1} - x^{2} + 1 d x = \frac{2}{3}

\int_{1}^{9} x^{2} - 1 d x = \frac{704}{3}

= \frac{2}{3} + \frac{704}{3}

Simplify

\frac{2}{3} + \frac{704}{3} : \frac{706}{3}

= \frac{706}{3}
