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 messag

[sage-support] Re: Notebook sign-up email

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

When you sign up for a Sage Notebook account, Sage sends an e-mail to the address you provide giving you a link to complete the registration. First of all, the "Sign up for a Sage Notebook account" says that the e-mail is needed if you forget your password, but makes no mention of the fact that t

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') 0 sage: limit(floor(x),x=0,dir='minus') 0 sage: [floor(each) for each in [-0.5,-0.1,-0.01]] [-1, -1, -1] Am I doing something wrong? thanks john perry --~--

[sage-support] Re: Converting/evaluating surd to float [ANSWER]

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.

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
