integral from-infinity to 0 of xe^{-5x}

\int_{- \infty}^{0} x e^{- 5 x} d x

diverges

Solution steps

\int_{- \infty}^{0} x e^{- 5 x} d x

Compute the indefinite integral:

\int x e^{- 5 x} d x = \frac{1}{25} (- 5 e^{- 5 x} x - e^{- 5 x}) + C

Compute the boundaries:

\int_{- \infty}^{0} x e^{- 5 x} d x =

= diverges

\int_{0}^{t} e^{- 2 x} sin (x) d x

\int_{0}^{1} x (1 - x)^{193} d x

\int_{- 1}^{0} x^{3} (4 x^{4} - 2)^{4} d x

\int_{1}^{6 x} (31 + t^{2}) d t

\int_{0}^{2} 30 x d x
