You should upgrade to a more recent version: ┌┐ │ SageMath version 8.0, Release Date: 2017-07-21 │ │ Type "notebook()" for the browser-based notebook interface.│ │ Type "help()" for help.

Re: [sage-devel] bug in cos ?!

Hello, In fact, it seems that in Sage 7.2, cos((p/q)*pi) gets reduced mod pi instead of 2pi, at least in cases where it does not simplify to square roots: sage: [cos(pi*(i+13)/13) - cos(pi*i/13) for i in range(0,50) if i%13!=0] == [0]*46 True It would be good to know what fixed that bug.

By the way, if the problem can be reduced to building the documentation (that is, if "make build" succeeds but "make" does not), another option would be to try "make doc-html-no-plot", or essentially equivalently do export SAGE_DOCBUILD_OPTS+=' --no-plot' make It is possible that the
