> What is the status of this ticket? Can it be closed as fixed?
no, the status is still the same (here with 3.4 since I cannot compile 4.1
from source on my laptop, but I guess the behaviour
in 4.1 is still the same):
{{{
sage: sin(10)
sin(10)
sage: Ei(10)
2492.22897624
sage: sin(x)
sin(x)
sage: Ei(x)
---------------------------------------------------------------------------
TypeError Traceback (most recent call

packages/sage/functions/transcendental.pyc in Ei(z)

}}}
To be coherent, Ei(10) should return Ei(10) as sin(10) returns sin(10),
and Ei(x) should return Ei(x) as sin(x) does return sin(x).
