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

Solution

\int_{- 2}^{1} ∣ x + 1 ∣ d x

Solution

\frac{5}{2}

+1

Decimal

2.5

Solution steps

\int_{- 2}^{1} ∣ x + 1 ∣ d x

Eliminate Absolutes

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

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

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

= \frac{1}{2} + 2

Simplify

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

= \frac{5}{2}
