2013-02-12 06:41:53 -0600 | answered a question | what happened to square_root() for rationals? I found online an old (ver 1.4.1) sage manual that says that square_root() for rationals: "Return the positive rational square root of self, or raises a ValueError if self is not a perfect square." So with this information is easy enough to code up a simple function to replace it. I do wonder why it went away and or if it has been renamed or replaced somehow. |

2013-02-11 08:21:08 -0600 | asked a question | what happened to square_root() for rationals? I have some old code that takes the square_root() of rational numbers. This function seems to be long gone. How do I replace its functionality? |

2012-11-08 04:46:07 -0600 | asked a question | load notebook files I have Sage installed and running OK. I am new to Sage and have two questions on using third party notebooks/code. I have a Sage notebook file called "sage_notebook.tar.bz2" that is included as part of a series of lectures I am stuying. This archive contains a single directory called "sage_notebook" 1) What do I need to do to read this into Sage? I also have some "worksheet" files. 2) What do I need to do to read a worksheet file into Sage? Thank you for getting me started? |
