Improper integral convergence
$\int_{\infty }^{0} xe^x dx$
Hi. Online calculators are telling me this converges to 1. My first instinct is that it diverges to negative infinity but I get what looks like an indeterminate form when I work through this. Can someone please explain why this converges to negative one? Thanks for your time.
here's what I have when after I substitute the bounds of the integral:
1  [ ($\infty $ 1) (1)]
