On to the good stuff: General comments and questions regarding this document should be sent by email to wst...@gmail.com. If you are able to provide suggested text, either to replace existing incorrect or unclear material, or additional text to supplement what's already available, we'd appreciate the contribution. </snip> ^^ Fix that notice to point to sage-support In the tutorial, all main page titles at the top seem to be lower case only. e.g. 2.10.2 systems of des using laplace transforms Should read Systems of DEs... (Firefox on Feisty) 2.10.2, few lines on: equatoins should read equations 3.9 saving and loading complete sessions Some of the yellow blocks of unix shell code around section 3, which should be <pre> is displaying with italics and font errors. In secion 3.9 for instance, the first yellow code block, only ~/tmp is in verbatim font, then follows italic, larger, sagesage: ... When I view page source I get (should that not all be class="verbatim"?): <div class="verbatim"><pre>~/tmp<span class="math"> sage sage: E = EllipticCurve('11a') sage: M = ModularSymbols(37) sage: a = 389 sage: t = M.T(2003).matrix(); t.charpoly().factor() _4 = (x - 2004) * (x - 12)^2 * (x + 54)^2 </pre>... 3.10 the notebook interface: "displaces the SAGE notebook webpage." should read "displays the SAGE notebook webpage." 4.2 GAP SAGE comes with GAP 4.4.7 for computational discrete mathematics, especially group theory. Should read "4.4.10" by now. 4.2 GAP (occurs elswhere too) The last line, <code><span class="math">SAGE_ROOT/local/lib/gap-4.4.7/pkg</code>. the _R is rendered as a subscript. The text is large and italic. Should be verbatim. 4.4 maxima The yellow code blocks show "sage.:" as the sage prompt, not "sage:". 5.1 loading and attaching sage files In particular, attach has the side effect of (auto-reload), very handy when debugging code, while load does not. ^^ What are the parentheses for? 6.1.2 how some python annoyances are resolved in sage Integer division: The expression 2/3 has much different behavior in Python than in any standard math system. In Python, if m and n are ints then m/n is also an int, namely the quotient of m divided by n . Therefore 2/3=0 . This illustrates how Python is similar to C in many ways (arrays are also indexed starting at 0). There has been talk in the Python community about changing Python so 2/3 returns the floating point number 0.6666..., and making 2//3 return 0 . ^^^^^^^^^ my comment: "from __future__ import" division will import the future behaviour, apparantly as of python3.0, which is / real division and // integer division. 6.3 how do i reference sage? If you write a paper using SAGE, please reference computations done with SAGE by including [SAGE], SAGE Mathematical Software, Version 2.6, http://www.sagemath.org ^^^ How about a function bibtex() similar to latex() which gives a bibtex entry? Coudl default to bibtex(sage) but could also provide bibtex(pari), bibtex(gp), bibtex(Singular), etc. If you happen to have just read straight through this tutorial, and have some sense of how long it took you, please let me know (email wst...@gmail.com). ^^^ Uhm, I did an hour or two yesterday and an hour or two today. Not sure. It's much more of a showcase() than a tutorial(). It has a heavy algebraic slant, and most students start learning more numerical work. ODE and Statistics examples would be great (I know, I know, submit them, I'm trying to learn SAGE!). We teach almost exclusively scipy at www.aims.ac.za now, but some lecturers still teach Maxima, Octave, and R, even Singular and GAP, and I would like to see them unified via SAGE, probably.
