Regarding special functions, I am obviously aware of the symbolic capabilities of Sage that are inherited from Maxima, which has a collection of stuff that can be dressed up one way or another. Maxima is hardly complete even with respect to the functions included, and the external list develo

Hi all, With respect to the spherical Bessel functions, I found that for some Real arguments one may find a bug related to the way Sage interprets Maxima numbers (which I personally don't understand). As I think it is related, here it is: https://groups.google.com/forum/#!searchin/sage-devel/m

If you look at the implementations you'll see that many of the functions have derivatives, arbitrary precision complex numerical evaluation, some simplification for specific input, and an interface to Maxima for integrals and other simplifications. The linked patches address these issues for fu
