return AddWithLimits.free_symbols.fget(self)
This method returns the symbols that will exist when the
        integral is evaluated. This is useful if one is trying to
        determine whether an integral depends on a certain
        symbol or not.

        Examples
        ========

        >>> from sympy import Integral
        >>> from sympy.abc import x, y
        >>> Integral(x, (x, y, 1)).free_symbols
        set([y])
