Not exactly. What I am saying is that Sage uses Maxima, another open source mathematics program, to do symbolic summation. I used Sage's instance of this program to see what happened with the underlying command which is passed to Maxima - and it turns out that the result is a hypergeometric function; since you like Wikipedia, here is their site about this http://en.wikipedia.org/wiki/Hypergeometric_function > What's the meaning of the previous texts?

This is the best Sage can currently do, probably because it lacks native support for hypergeometric functions (?). It looks like Maxima can do this, though, using the syntax I describe. You can always use a Maxima session from inside Sage by doing maxima_console(), or in the notebook with %maxima at the beginning of a cell. > > > Can I find radius of convergence of series?

I see. I don't know how easy this might be in general, except of course by using the usual tests. The thread http://www.mail-archive.com/[email protected]/msg06784.html seems to have something related, though I think it focuses on inequalities. Someone else might know more; I don't think this is built in functionality. - kcrisman -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
