Well, I tested the worksheet and with Safari on OSX I also had to manually select UTF-8 to see the comments correctly, so it isn't only IE :) Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

[sage-support] interact input box problem
Dear Support, On sagenb.org, try making an interact with an input box explicitly defined, e.g. @interact def plotfunction(f=input_box(x^2)): P=plot(f,0,1) show(P) It works fine in the sense that whatever you type in does what it should. But what's up with how the input box appears? It's even worse on my box (PPC OSX.4) - the initial input does not show up *at all* in the box, though again the plot is fine and once you type something in it behaves normally. Any suggestions as to what I'm doing wrong would be appreciated. Or is it still fallout from TinyMCE or something like that?

[sage-support] Re: How set UTF8 on the sage Notebook published page automatically?
Thanks to reply my post. Actually, in firefox it works well. But as you know, Windows IE is popular Web browser. Therefore I can't say 'You should use firefox to see this comments' to all users. I think there is no the meta html code to say about page. http://www.sagenb.org/home/pub/220/ I wrote comments in Korean at that page. But I can't read this comment on the IE7, because IE7 don't know about encoding. So it set EUC-KR, because this machine OS is Windows XP Korea. I suggests that the meta html code is added to all notebook page like this Then Web browser know this page's encoding is UTF-8. - 누구나가 다, 자기 옆에서 눈물을 흘리며 신음하는 불행한 사람들에 비해 자기가 훨씬 더 불행하다고 생각하지요. 이게 바로 우리 가련한 인간들의 오만 중의 하나입니다. - LE COMTE DE MONTECRISTO Nickname : NoSyu School of Information & Communication Engineering, SungKyunKwan University blog : http://nosyu.pe.kr On 2월9일, 오전11시05분, Dan Drake wrote: > Hello, > > > > On Fri, 06 Feb 2009 at 06:27AM -0800, NoSyu wrote: > > Hello~ > > > I test the sage on the sage Notebook homepage. > > >http://www.sagenb.org > > > So I wrote the code and comments and published it. > > >http://www.sagenb.org/home/pub/209/ > > > I'm Korean and I want to show my code to my friends.

I agree with Harald's idea -- if you have lengthy computations in your document and fix a misspelling, it would be annoying to wait while Sage recomputes everything. Also, I think many TeX distributions disable shell-escape by default, and we would have to get users to re-enable it. Also, the shell escape stuff wouldn't work with my current plan for "SageTeX remote", which would use the Sage API to access a remote copy of Sage. Also, I think each shell escape call invokes a new command, which would make it impossible/very difficult to maintain state. Right now, you can repeatedly refer to an existing Sage variable throughout your document; if each shell escape was a blank slate, that would be tedious to type, and increase the running time even more.

Since you're lucky and all conjugates are expressible in terms of
radicals, the following
easily gives all 8:
sage: t = sqrt(2-sqrt(2)) + i*sqrt(sqrt(2)-1)
sage: f = t.minpoly(); f
x^8 - 12*x^6 + 6*x^4 - 12*x^2 + 1
sage: solve(SR(f)==0,x)
[x == -sqrt(2*2^(1/4)*sqrt(2*sqrt(2) + 3) + 2*sqrt(2) + 3), x ==
sqrt(2*2^(1/4)*sqrt(2*sqrt(2) + 3) + 2*sqrt(2) + 3), x ==
-sqrt(-2*2^(1/4)*sqrt(2*sqrt(2) + 3) + 2*sqrt(2) + 3), x ==

-sqrt(-2*2^(1/4)*sqrt(3 - 2*sqrt(2))*I - 2*sqrt(2) + 3), x ==

[sage-support] Conjugates
Hello,
A friend of mine wanted to know all the conjugates of a particular
algebraic number, and I was trying to figure out the right way of
finding them with Sage. Sorry if this is too trivial a question.
This is what I tried:
sage: t = sqrt(2-sqrt(2)) + i*sqrt(sqrt(2)-1)
sage: p = t.minpoly(); p
x^8 - 12*x^6 + 6*x^4 - 12*x^2 + 1
sage: K. = NumberField(p)
sage: a.galois_conjugates(K)
[a, -a, a^7 - 12*a^5 + 6*a^3 - 12*a, -a^7 + 12*a^5 - 6*a^3 + 12*a]
I copied this result into a text editor to replace 'a' with 'x', then
did
sage: ts = [q(t).exp_simplify() for q in [x, -x, x^7 - 12*x^5 +
6*x^3 - 12*x, -x^7 + 12*x^5 - 6*x^3 + 12*x]]; ts
[sqrt(sqrt(2) - 1)*I + sqrt(2 - sqrt(2)),
-sqrt(sqrt(2) - 1)*I - sqrt(2 - sqrt(2)),
sqrt(sqrt(2) - 1)*I - sqrt(2 - sqrt(2)),
sqrt(2 - sqrt(2)) - sqrt(sqrt(2) - 1)*I]
which are indeed conjugates, so it's good. But what about the other 4
roots? I guess the problem is that NumberField(p) is not big enough to
contain all the conjugates. Trying
sage: a.galois_conjugates(CC)
does give all 8 conjugates, but in decimal numbers, not in terms of
radicals, while one can get all 8 by using:
sage: a.galois_conjugates(QQ[t,i])
[a^7 + (-12)*a^5 + 6*a^3 + (-12)*a,
(-1/8*I - 3/8)*a^7 + (11/8*I + 35/8)*a^5 + (5/8*I - 5/8)*a^3 +
(17/8*I + 21/8)*a,
(1/8*I - 3/8)*a^7 + (-11/8*I + 35/8)*a^5 + (-5/8*I - 5/8)*a^3 +
(-17/8*I + 21/8)*a,
(-1)*a,
a,
(-1/8*I + 3/8)*a^7 + (11/8*I - 35/8)*a^5 + (5/8*I + 5/8)*a^3 +
(17/8*I - 21/8)*a,
(1/8*I + 3/8)*a^7 + (-11/8*I - 35/8)*a^5 + (-5/8*I + 5/8)*a^3 +
(-17/8*I - 21/8)*a,
(-1)*a^7 + 12*a^5 + (-6)*a^3 + 12*a]
after which replacing the 'a's with 'x' and pasting it back as above
gives all the conjugates:
sage: ts = [q(t).exp_simplify() for q in (--replaced expression,
snipped--) ]; ts
[sqrt(sqrt(2) - 1)*I - sqrt(2 - sqrt(2)),
(-sqrt(2) - 1)*sqrt(sqrt(2) - 1) + (-sqrt(2) - 1)*sqrt(2 - sqrt
(2)),
sqrt(sqrt(2) - 1)*(sqrt(2) + 1) + (-sqrt(2) - 1)*sqrt(2 - sqrt
(2)),
-sqrt(sqrt(2) - 1)*I - sqrt(2 - sqrt(2)),
sqrt(sqrt(2) - 1)*I + sqrt(2 - sqrt(2)),
sqrt(2 - sqrt(2))*(sqrt(2) + 1) + (-sqrt(2) - 1)*sqrt(sqrt(2) -
1),
sqrt(sqrt(2) - 1)*(sqrt(2) + 1) + sqrt(2 - sqrt(2))*(sqrt(2) +
1),
sqrt(2 - sqrt(2)) - sqrt(sqrt(2) - 1)*I]
So Sage completely helped with the question, which is great. :-)
My question is whether there is a better way to do this. In
particular:
1. Is there a way to avoid manually replacing 'a' with 'x' as above?
2. Here, K=NumberField(p) was not a big enough field, but K[i] was. Is
it possible to automatically choose an appropriately big field? [I
tried a.galois_conjugates(K.galois_closure('a1')) as in the
documentation, but wasn't sure how to interpret the result.]
3. It seems that while p.roots() returns an empty list and
p.complex_roots() returns the roots in decimals,
sage: (x^8 - 12*x^6 + 6*x^4 - 12*x^2 + 1).roots()
does find all roots, in terms of radicals. So might it be possible to
write a conjugates() function in cases where the polynomial *can* be
solved with radicals?

No, if you do not set certain env variables tests create tmp files in $SAGE_ROOT/tmp, so if the user running the test does not have write permission there the test will fail to run. So either run the tests as root if you used that to build Sage or alternatively set SAGE_TESTDIR to some place where you have write access (IIRC the directoy needs to exist), i.e. export SAGE_TESTDIR=$HOME/tmp There are known problem with the second approach we haven't fixed yet - see http://trac.sagemath.org/sage_trac/ticket/5155 > Regards > > Earl Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

I hope the following is helpful. The only reason for an end user to install the gnuplot package is of they can't install it any other way. Sage doesn't do any binary linking at all to gnuplot. As long as a gnuplot command is installed and in their path, things should work. The user does have some gnuplot installed, evidently, but it's probably not setup to run by typing "gnuplot" in Terminal. They probably need to make a script called "gnuplot" in their PATH and put something like this in it: -- #!/bin/sh path/to/gnuplot $@ - where /path/to/gnuplot is the path to their gnuplot install.

[sage-support] Re: Errors in make test run on fresh sage install.
Hello Michael I'm running Bash shell. Tried a couple more times to make this work and while doing so noticed something interesting. When I installed this thing I placed it into a "/home/earl" user directory however I ran the make as root as it would not run as normal user. I just tried a couple of different cycles of running root and then user and am getting much different result. as root it looks like this below linux-gqpn:/home/earl/programs/sage-3.2.3 # ./sage -t devel/sage/sage/ rings/finite_field_ntl_gf2e.pyx sage -t "devel/sage/sage/rings/finite_field_ntl_gf2e.pyx" ** File "/home/earl/programs/sage-3.2.3/devel/sage/sage/rings/ finite_field_ntl_gf2e.pyx", line 171: sage: k.modulus() Expected: x^17 + x^16 + x^15 + x^10 + x^8 + x^6 + x^4 + x^3 + x^2 + x + 1 Got: x^17 + x^3 + 1 ** 1 items had failures: 1 of 10 in __main__.example_2 ***Test Failed*** 1 failures.

He is using gnuplot for some legacy-code reasons. The one error log excerpt below is useless. Without install.log there is nothing one can do. We should really change the error message, especially the word "relevant" in "explaining the problem and send the relevant part of" since more and more new Sage users have little understanding what part of the log is required to debug the problem. We also need to stop asking people to send the log to the list since I am not looking forward to the next person sending out a multi MB uncompressed install.log :p Overall it looks like some kind of problem related to X, but I would not be surprised if macports and/or Fink is involved here. > -Marshall Cheers, Michael > -- Forwarded message -- > From: "Patrick E.
