Is there any kind of general theory we can use for these integrals?
Kind of like how specint works by converting the integrand to a
hypergeometric form and integrating that? I mostly just curious.
Another thing that we might want to look into is TILU (table of
integrals by lookup). Richard Fateman has obtained permission for us to
use that and he sent out the code sometime ago. I meant to look into
integrating that into maxima, but I never got around to it. (Some
design issues need investigating, like where the integrals are stored.
As part of maxima? Some webserver somewhere? Something else?)
