Yes, I read your previous post. I just want to ensure myself that there is really no "another method" out there. Thank you for telling me about what happened to the mathematician :smile:
Thank you for all of your help.
Best regards,

Well, if I just tried to find out the answer, that fact would be enough for me. But, I want to know how in the past someone would be able to obtain that answer. Suppose a mathematician in the past encountered the same class of problem. Of course, the mathematician would have tried the...
I have taken a look at the page on Wikipedia but it does not explain anything how a series of non-terminating integration by parts can be transformed to an exponential integral.
Could you please tell me how to do the transformation? Or, is there any pointer to a webpage that shows how to do...
