Comment (by rws):
Sympy's "antiderivative at" will not have an equivalent in Sage:
{{{
sage: sympy.Integral(sympy.sin(x),(x,0)).doit()
-1
sage: integral(sin(x),x,0,hold=True)
integrate(sin(x), x, x, 0)
sage: _.simplify()
cos(x) - 1
}}}
We have also a problem with the Sage-->Sympy direction.
{{{
sage: sympy.sympify(integral(sin(x),x,hold=True))
Integral(sin(x), x)
sage: sympy.sympify(integral(sin(x),x,0,hold=True))
...
ValueError: Invalid limits given: (x, x, 0)
sage: sympy.sympify(integral(sin(x),x,0,1,hold=True))
...
ValueError: Invalid limits given: (x, 0, 1)
}}}
