[sage-support] Getting a Dirichlet series for mu

2011-05-06 Thread kcrisman
I tried L = Dokchitser(conductor=1, gammaV=[0], weight=1, eps=1) L.init_coeffs('moebius(k)') to get the Dirichlet series of the Moebius mu function. That didn't work: L(2); (1/(pi^2/6)).n() 0.0741344280534404 0.607927101854027 But maybe there is some other pole or something I need to

Actually, never mind all that. Mayavi simply rufuses to work properly on my system and the documentation on sage integration is just too scant. I will just have to make do with implicit_plot3d and the like. I was wondering if there is any way of integrating an implicit_plot3d plot and a slice

[sage-support] Shift-enter doesn't work (and 'evaluate' doesn't show up)

2011-05-06 Thread Harmor
Hello Friends, thanks in advance for your help. I just installed sage on my ubuntu desktop after dealing with sort of a problem with the number of inodes in my file system. It turns out that after starting the sage notebook the shift-enter evaluation method doesn't work and it doesn't appear to
