hopefully I've not misspelled your name.
its done.
I need to test more. Ex:
{{{
Failed example:
[giacpy-0.5.6] f=1/(5+cos(4*x));f.int(x)
[giacpy-0.5.6] Expected:
[giacpy-0.5.6]
1/2/(2*sqrt(6))*(atan(2*tan(4*x/2)/sqrt(6))+pi*floor(4*x/2/pi+1/2))
[giacpy-0.5.6] Got:
[giacpy-0.5.6]
1/2/(2*sqrt(6))*(atan((-sqrt(6)*sin(4*x)+2*sin(4*x))/(sqrt(6)*cos(4*x)+sqrt(6)-2*cos(4*x)+2))+4*x/2)
}}}
