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

Solution

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

Solution

- \frac{1}{3}

+1

Decimal

- 0.33333 \dots

Solution steps

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

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

= 2 - \frac{7}{3}

Simplify

2 - \frac{7}{3} : - \frac{1}{3}

= - \frac{1}{3}
