integral from-1 to 1 of (|x|+x)e^{-|x|}

\int_{- 1}^{1} (∣ x ∣ + x) e^{- ∣ x ∣} d x

2 (- \frac{2}{e} + 1)

Solution steps

\int_{- 1}^{1} (∣ x ∣ + x) e^{- ∣ x ∣} d x

Eliminate Absolutes

= \int_{- 1}^{0} (- x + x) e^{- (- x)} d x + \int_{0}^{1} (x + x) e^{- x} d x

\int_{- 1}^{0} (- x + x) e^{- (- x)} d x = 0

\int_{0}^{1} (x + x) e^{- x} d x = 2 (- \frac{2}{e} + 1)

= 0 + 2 (- \frac{2}{e} + 1)

Simplify

= 2 (- \frac{2}{e} + 1)

\int_{2}^{5} 3 x^{2} d x

\int_{π}^{2 π} (x - 2 sin (x)) d x

\int_{1}^{7} \frac{x + x ^{3}}{x} d x

\int_{0}^{y} 2 y d y
