logging a function's argument

Code:

argx(a):=begin l.append(a); return a; end;
l:=[];
romberg('sin(cos(argx(x)))',x,-1,1);

Thanks, that's just what I was looking for.

It works with romberg() and int() with finite limits, but not int() with infinite limits. Is there a way to call gaussquad() directly on the Prime like you can in XCAS?

I still couldn't get fsolve() to work, but I am pleased to get integration working.
