Dear all,
I would like to differentiate functions that contain unknown functions
of the variable. This explanation probably doesn't mean much, so I'd
better show an example:
sage: var('c x y t')
(c, x, y, t)
sage: x=function('x',t)
sage: y=function('y',t)
sage: f=c*x*y
sage: diff(f,t)

Hi Robert,
I looked at your build log you send me off list and lcalc failed to
build. I suspect it is due to some CFLAG option we set, namely using -
static-libgcc. According to the log this was added a while back, but
I see no reason to add it at all. Can you take the spkg at

Hi there,
Q: How do you evaluate or convert a surd value generated by SAGE into
numerical output?
A: Use the .n() method. i.e.
sage: sin(10)
sin(10)
sage: sin(10).n()
-0.544021110889370
This bugged me for ages when trying to export data to another program.
Perhaps this should be made clearer
Hi:
The following gives a patch not under root abort error which I was wondering
if anyone could explain.
(1) I create a clone
(2) download a patch from trac (by clicking on the link at the bottom
of the patch
page and selecting download)

I don't think that sin(10) is a surd, though it is certainly
irrational and probably even transcendental.
If you look up definitions of surd online you get a quite incredible
collection of conflicting answers, many of which (even in high school
revision guides) are almost complete nonsense.
Hello,
I'm quite sure this is a bug, but I can't find a ticket for it.
sage: limit(floor(x),x=0)
0
sage: limit(floor(x),x=0,dir='plus')

sage: limit(floor(x),x=0,dir='minus')

sage: [floor(each) for each in [-0.5,-0.1,-0.01]]
[-1, -1, -1]
Am I doing something wrong?
thanks

That looks to me like a bug caused by an underlying bug in maxima.

When you sign up for a Sage Notebook account, Sage sends an e-mail to

Greg,
It's not clear from your message, but are you running Sage locally or
are you trying to get an account on a remote Sage installation?
If it is a local Sage installation then no emails need to be sent for
any reason in order to have the notebook interface work.
Clarify things if you don't
I am running a Sage notebook server for my students. Every time one of
my students creates an account, the notebook sends the student an
e-mail with a link to confirm their e-mail address. However, that
e-mail gets bounced back to the server since my machine is not
authorized to send e-mail
Michael,
That did the trick. Sage finished compiling and passed all its tests.
Thank you very much.
