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

    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.
