Integral of dx/Sqrt[exp(-x)+x+c]

  1. Feb 11, 2009 #1
    Does anybody know if it is possible to find the anti-derivative of 1/Sqrt[exp(-x)+x+c] with respect to x. Mathematica was unable to compute it. Would it be possible to convert it into a form where residue theory is applicable?

    Residue theory is usually only good for computing infinite integrals, or integrals from 0 to 2pi. I'm not aware of any way to compute a general anti-derivative using it

    What if I made it a definite integral...and integrated from xa to xb.

    and then apply some sort of conformal mapping to change it to an infinite integral
