2015-03-11 17:39:28 +0100 | commented answer | improper integral error? But the correct answer is a numerical value or exact expression pi^2/4. So, algorithm = 'mathematica_free' doesn't work. |
2015-03-11 14:33:19 +0100 | asked a question | improper integral error? Is there an alternative way to calculate this improper integral? integral(log(x)/(x^2 - 1),x,0,infinity) the integral is convergent to pi^2/4 but Sage says divergent. |

2015-02-24 20:49:44 +0100 | asked a question | RuntimeError: should never launch viewer in embedded mode In Sage version 6.3, next exemple is OK: L = [plot(k*x,(x,-1,1)) for k in [1..3]];G = graphics_array(L);G.show(figsize=[5,3]) But in Sage version 6.4 and 6.5, we have error message RuntimeError: should never launch viewer in embedded mode Is there something wrong?

2014-07-10 02:14:24 +0100 | commented answer | bug pdflatex sage-6.2 ? Thank you very much. But we can't modify Sage ova version for windows under VirtualBox. We can't install pdflatex in ova version for windows. Am I not right? |
2014-07-08 18:50:20 +0100 | asked a question | bug pdflatex sage-6.2 ? Hi guys. In sage 6.1.1 and earlier you can evaluate without problems sage: %latex sage: This is {\LaTeX} but in sage 6.2 (with VM or native linux) we get the error: Error: PDFLaTeX does not seem to be installed. Download it from ctan.org and try again. None This is a bug? Is sage-6.2 an incomplete installation? |
2014-07-08 18:31:28 +0100 | commented question | Error: PDFLaTeX I noticed the same error. In sage 6.1.1 and earlier under windows you can evaluate without any problems sage: % latex sage: This is {\ LaTeX} but not in sage 6.2 With Sage notebook installed in a VM from sage.-6-2.ova we can't install anything. Does the sage-6.2.ova is incomplete? Any tips? Thank you |
