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

Solution

\int_{- 1}^{1} ∣ 2 x - 1 ∣ d x

Solution

\frac{5}{2}

+1

Decimal

2.5

Solution steps

\int_{- 1}^{1} ∣ 2 x - 1 ∣ d x

Eliminate Absolutes

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

\int_{- 1}^{\frac{1}{2}} - 2 x + 1 d x = \frac{9}{4}

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

= \frac{9}{4} + \frac{1}{4}

Simplify

\frac{9}{4} + \frac{1}{4} : \frac{5}{2}

= \frac{5}{2}
