integral from-1 to 3 of x/(|x|)

Solution

\int_{- 1}^{3} \frac{x}{∣ x ∣} d x

Solution

2

Solution steps

\int_{- 1}^{3} \frac{x}{∣ x ∣} d x

Eliminate Absolutes

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

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

\int_{0}^{3} \frac{x}{x} d x = 3

= - 1 + 3

Simplify

= 2
