Hi, I'm testing sage, the expressions and I play with expr.expand().
After test = 3*x, I find test.expand? and get the help text, and test.expand?? and the main call about expand. Then emacs goes to expression.pyx at the lines defining the interface (outer) function expand. In this code I find : _sig_on cdef GEx x = self._gobj.expand(0) _sig_off return new_Expression_from_GEx(self._parent, x) Where is this mysterious method self._gobj.expand(0) ?
