In Sage, 'x' is pre-defined (which the weighted majority of Sage
developers considers a feature, not a bug :-).
Namely, if you start sage, then you get
sage: type(x)
<class 'sage.calculus.calculus.SymbolicVariable'>
I guess that in a Sage script, this assignment of x is not done, so
that you have to explicitely do
x=var('x')
in your script; I don't know if you need to import "var".
Best regards,
Simon
