Integration of exponentials with a fractional power?

  1. Dec 22, 2008 #1
    Could anyone explain to me the rule when Integrating of exponentials with a fractional power?

    e.g. ue to the power of -t/T. ue^-t/T

    Thanks in advance

    Welcome to PF,

    What are we integrating with respect to?

    Many people will not open "doc" files because they are notorious for viruses. Please just answer the question.

    It looks to me like this just requires a simple substitution. Assuming you are integrating with respect to t, to integrate e^(t/T), let u= t/T. Then du= dt/T or dt= du/T.
