Comment #5 on issue 2230 by [email protected]: Problem in is_Function ans is_Number
http://code.google.com/p/sympy/issues/detail?id=2230
Not necessarily clearer, because in this case I would expect to have is_Application for sin(1) case (in early days of SymPy we had applied and unapplied functions). But anyway, look at this:
In [1]: sin.nargs Out[1]: 1 In [2]: sin(1).nargs Out[2]: 1 This suggests that I should be allowed to do this: In [3]: sin(1)(1) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/mateusz/repo/git/sympy/<ipython console> in <module>() TypeError: 'sin' object is not callable -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
