Gruntz uses the series code extensively and I've encountered the following error quite a few times:-
PoleError: Asymptotic expansion of cos around [oo] is not implemented. If you use limit, answer is evaluated correctly to 0. However there might be cases where we might need expansion of sin and cos to correctly evaluate limit. Since sin and cos do not converge at infinity and are bounded functions, in my opinion asymptotic expansion of sin and cos at [oo] should be simply Order(1), right? I maybe wrong, but that would enable Gruntz to give the correct result. -- You received this message because you are subscribed to the Google Groups "sympy" group.
