| Jul 26, 2015 at 17:16 | comment | added | Jack LaVigne | When I compute the inidivual terms Gamma[4n[Mu]], Gamma[4n[Nu]], and Hypergeometric1F1Regularized[4n[Nu],4n([Mu]+[Nu]),4ns] I get 362880, 362880 and 1.24459*10^47 for n=2500, s=0.0001, [Nu]=0.001, [Mu]=0.001. Yet when I multiply all three together I get 1.7953*10^-6. This leaves me totally confused. | |

| Jul 26, 2015 at 17:15 | comment | added | Jack LaVigne | I am mystified by the Hypergeometric1F1Regularized function. I would like to put this in an answer so you can see my text better, but I really have a question so think it would be wrong to post it as an answer. It is too long for one comment so I will break it into parts. | |

@Dr.WolfgangHintze Thanks for the observation and response, that might save me some trouble. (That, or double it, if both Integrater AND NIntegrate are derelict. We'll see.)

| Jan 10, 2015 at 22:29 | comment | added | Dr. Wolfgang Hintze | @Daniel: I don't think so. Integrate behaves well (Version 8) (see my answer). | |

I suspect Integrate is coming up with a bad antiderivative. Will investigate.
