R.<x> = PowerSeries(SR)
f = 1 + O(x^2)
f.derivative()
This gives us `O(x^1)` as we would expect. However, if we do
f = O(x^0)
f.derivative()
we get `O(x^-1)` instead of `O(x^0)` again. Is this a bug or am I missing something?NullInfinitySun, 15 Jan 2017 15:16:30 +0100https://ask.sagemath.org/question/36301/
