I think this: http://www.sagemath.org/doc/developer/producing_patches.html should be merged into the "Walking through the Development Process" section. I found it a much better guide for patch creation. -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from thi

I noticed a couple of things on sage-devel recently about integration with Maxima. It appears Maxima can't do either of these two. (Well, it does the second one, but leaves it in a overly complex form, that Sage's n(). can't even use). integrate( sqrt(x^2+4)/(x^2+1), x ) integrate(log(1+x)/(x^2+1

[sage-devel] Updating the Developer's Walk-Through

2011-02-20 Thread Rob Beezer
I'm inclined to update the "Walking Through the Development Process" section of the Developer Guide. I've had some feedback (in-person) and have seen a few thoughtful comments in various places in sage-devel. Other than mentioning new features (like "hg qpush --move" (!) and the patchbot) and tec

[sage-devel] cddlib fails to build if autoconf is not installed.

2011-02-20 Thread David Kirkby
Recently in order to make some constructive comments on a trac ticket I needed to build a part of it without autoconf, so I temporarily rename autoconf to something else. Needless to say I forgot to put it back, which was lucky, as I seem to have uncovered a bug. Without autoconf, the cddlib pack

Re: [sage-devel] Should .resultant() and .discriminant() return objects in the same ring or in a smaller one?

2011-02-20 Thread John Cremona
One difference is that in the multivariable case, having the return value in the ring with fewer variables would require that ring to be created. I don't know how much of an over head that would be. Also, whether Sage would automatically be ably work with the three subrings (say) k[x,y], k[x,z],

I have recently opened track ticket 10799 solving some problems with coumputing resultants in univariate polynomial rings. Now i plan to implement the .discriminant() method for polynomials in multivariable rings. But i have a doubt now. The method .resultant() returns a polynomial in the same ring
