Hi,
I tried the following in Maxima 5.19.2 and it doesn't seem to work:
(%i1) load("solve_rat_ineq.mac");
(%o1)
C:/PROGRA~1/MAXIMA~1.2/share/maxima/5.19.2/share/contrib/solve_rat_ineq.mac
(%i2) solve_rat_ineq((2*x-1)/(2*x*(x^2+1))>0);
Division by 0
#0: solve_rat_ineq(ineq=(2*x-1)/(2*x*(x^2+1)) > 0)(solve_rat_ineq.mac line
87)
-- an error. To debug this try debugmode(true);
Maybe a bug? Thanks,
regards
Andrea
