Hello, I'm new to Mathematica and I want to compute a serie expantion of ArcTan(n Pi + Pi/2 + O(1)) (The O is a big O and is taken when n goes to Infinity) I dont know how to input O(1) in Mathematica. For example O[n,Infinity]^0 simplifies to 1 which is not what I want. Thanks for the help. Francois
