[sage-support] Re: Can't plot with sage: Maxima crashed
Thanks for your reply! So I should either download source or wait for Ubuntu binaries. Could be please suggest an option after considering the following: I want only a stable version. I am currently not interested in the bleeding edge of sage, at least for a few months. (So should I download a previous version?) I have an interconnection that's fast, BUT very limited data transfer limit. So which is easier to upgrade, source or binaries? Is there any way I can download only the changes for the next version (whenever I would want it) and not have to download 300 MB each time I want to upgrade? Also, could you then explain for which linux distos the Debian version will work on, since I downloaded the Debian after I saw this in http://www.sagemath.org/bin/linux/32bit/README.txt: NOTE: The Debian version will likely work on many other Linux distributions, since it was built on a minimal Debian install. Thanks again for your help! Umang William Stein wrote: On Sat, Sep 20, 2008 at 3:59 AM, Umang [EMAIL PROTECTED] wrote: Hi!

I'll make sure the binaries set for 3.1.2 contains an ubuntu 32-bit binary. These binaries will come out within a day. sage: install_scripts('/usr/bin') After that, when I wanted to plot (I was going through the manual). sage: plot(cos, (-5,5)) Maxima crashed -- automatically restarting.

So I have a few questions: How can I undo install_scripts('/usr/bin') (because I'd like to reinstall completely)? This is not necessary. These scripts are all just 2-3 liners that just call sage with an appropriate command line option. What can I do about this problem? Either build from source or wait for an ubuntu binary. How do I plot? What more information would you like to understand this error? Thanks a lot!

[sage-support] question on using integral() in sage. Fourier transform of unit step function.
Hello; I am a sage newbie. I'd like to find out how to make Sage give me this same result that I get in Mathematica. This is what I typed (I do not know how to cut/paste from the VMWare player console to her yet, so if there is a typo it is because of this). f=var('f') assume(f0) integral( e^(-I * 2 * pi * f * t), t , 0 , Infinity) The answer I get starts with limit(sin(2*pi*f*t),t, etc...etc... Is there a way to tell Sage to give me this answer I get from Mathematica? Assuming[Im[f] 0, Integrate[Exp[(-I)*2*Pi*f*t], {t, 0, Infinity}]] -(I/(2*f*Pi)) Thanks, Nasser --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

[sage-support] Sage Days 11: November 7-10, Austin, Texas
Hi all, This is a reminder that Sage Days 11 is fast approaching! The topic is Special functions and computational number theory meet scientific computing. The plan is to bring together a bunch of number theorists and scientific computing/supercomputing experts, and Austin's incredible supercomputing facilities make this the perfect place for it. If you're new to Sage, and interested in this topic, attending a Sage Days is the perfect way to get more involved. (For those of you who've been around a while, you know the drill -- just go ahead and skip this paragraph.) Sage Days are friendly and very intensive focused development workshops, which are probably fairly different from other math-related conferences and workshops you've attended. There are usually only one to two talks per day, in order to allow for the maximum time for working discussions and coding sprints. The groups are organized on the first day, and there are regular progress reports throughout the workshop. We have a webpage: http://www.math.utexas.edu/sage and a wiki page: http://wiki.sagemath.org/days11 If you're planning on joining us in Austin, please register soon at http://www.ma.utexas.edu/sage/rform1.php, and add your name to the wiki. We do have some limited funding available, so please let us know if you'll need funding. We have a block of rooms reserved at the Doubletree Guest Suites in Austin, and we'll let you know more details on that soon. If you have any questions, feel free to email me or any of the other organizers!
