Comment #3 on issue 2131 by [email protected]: failing limit http://code.google.com/p/sympy/issues/detail?id=2131
In original expression there was division by "x". So, instead "In [8]" must be: In [9]: (_/x).limit(x, 0) Out[9]: nan That is, there is no self-contradiction. In [10]: (diff(x**3*sin(1/x), x) / x).cancel() Out[10]: -cos(1/x) + 3*x*sin(1/x) The limit in this point does not exist indeed. (due to the cos() term ) Essential singularity exist only: [-1, +1]. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
