Perhaps this bug is not a new problem. The answer of Maxima depends on the flag triginversers. (%i36) integrate(sqrt(sin(t)^2+cos(t)^2),t,0,2*%pi),triginverses:true; (%o36) %pi (%i37) integrate(sqrt(sin(t)^2+cos(t)^2),t,0,2*%pi),triginverses:all; (%o37) 2 %pi Okay, let's check if this

(%i1) triginverses; (%o1) all (%i2) asin(sin(x)); (%o2) x (%i3) asin(sin(x)), triginverses=true; (%o3) asin(sin(x)) Is that going to affect any Sage stuff if we revert to 'all'? (Presumably not, since there don't seem to have been any other complaints about this.) Sorry for all the

This was the Maxima upgrade, for sure. It is not in 4.1.1 (just checked) and is in the latest CVS of Maxima (just checked that, too). I can't submit a bug report to them right now - can you email their list (I think you're on it?) and see if they know about it? - kcrisman

to me, this looks like a strong encouragement to provide sage 4.1.3 with a couple of bugfixes (also considering something that could arise from the new notebook) anytime very soon: I don't think it is a good idea to have a release with such a serious bug, out for too long... the problem is that I
