integral from-infinity to 0 of e^{-|8x|}

\int_{- \infty}^{0} e^{- ∣ 8 x ∣} d x

\frac{1}{8}

Decimal Notation

0.125

Solution steps

\int_{- \infty}^{0} e^{- ∣ 8 x ∣} d x

Eliminate Absolutes

= \int_{- \infty}^{0} e^{- (- 8 x)} d x

Compute the indefinite integral:

\int e^{- (- 8 x)} d x = \frac{1}{8} e^{8 x} + C

Compute the boundaries:

\int_{- \infty}^{0} e^{- (- 8 x)} d x = \frac{1}{8} - 0

= \frac{1}{8} - 0

Simplify

= \frac{1}{8}

\int_{0}^{1} \frac{2}{4 x + 5} d x

\int_{1}^{3} (x + \frac{1}{x}) (x^{2} - 3 x) d x

\int_{1}^{6} x + 3 d x

\int_{1}^{\infty} \frac{1}{x e ^{x}} d x
