(self)
return self._args
Returns a tuple of arguments of 'self'.

        Examples
        ========

        >>> from sympy import cot
        >>> from sympy.abc import x, y

        >>> cot(x).args
        (x,)

        >>> cot(x).args[0]
        x

        >>> (x*y).args
        (x, y)

        >>> (x*y).args[1]
        y

        Notes
        =====

        Never use self._args, always use self.args.
        Only use _args in __new__ when creating a new function.
        Don't override .args() from Basic (so that it's easy to
        change the interface in the future if needed).
