This is a Maxima bug; running this in Sage's version of Maxima gives (%i5) integrate(sqrt(cos(2*(x)))/sin(x),x);
sign: argument cannot be imaginary; found %i -- an error. To debug this try: debugmode(true); The same error is produced by the latest Maxima: Maxima 5.41.0 http://maxima.sourceforge.net using Lisp SBCL 1.4.4 Distributed under the GNU Public License. See the file COPYING. Dedicated to the memory of William Schelter. The function bug_report() provides bug reporting information. (%i1) integrate(sqrt(cos(2*(x)))/sin(x),x); sign: argument cannot be imaginary; found %i -- an error.
