Hello; When using Fricas directly, I always set

      setSimplifyDenomsFlag(true)

Before calling integrate. For example

        setSimplifyDenomsFlag(true)           
        integrate((x+(1+x)^(1/2))^(1/2)/(x^2+1)/(1+x)^(1/2),x)

Otherwise, many integrals will hang or take too much time. Since I have a timeout of 3 minutes, it will fail.

But from sage, I could only do

           integrate((x+(1+x)^(1/2))^(1/2)/(x^2+1)/(1+x)^(1/2),x,algorithm="fricas")

Is there a way to somewhere pass this command to fricas along with the integrate command? i.e. is there a way to pass 2 commands to be executed in same transaction to the other CAS? Because without being able to set this flag before calling integrate, this will not work. By default this flag is set to false in Fricas for some reason.

Thank you

ps. I asked at the Fricas forum if there is a way to rebuild fricas on Linux with this flag set to true. If so, I can rebuild-fricas. But I do not know now. I asked here fyi
