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

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

\frac{20}{3}

Decimal

6.66666 \dots

Solution steps

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

Eliminate Absolutes

= \int_{- 2}^{0} - x - (x^{2} - 2) d x + \int_{0}^{2} x - (x^{2} - 2) d x

\int_{- 2}^{0} - x - (x^{2} - 2) d x = \frac{10}{3}

\int_{0}^{2} x - (x^{2} - 2) d x = \frac{10}{3}

= \frac{10}{3} + \frac{10}{3}

Simplify

\frac{10}{3} + \frac{10}{3} : \frac{20}{3}

= \frac{20}{3}

\int_{0}^{2 x} cos (x^{2}) d x

\int_{0}^{t} u e^{2 u} cos (3 u) d u

\int_{0}^{π} x ∣ cos (x) ∣ d x

\int_{0}^{1} x \frac{x}{1 - x} d x

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