comment Expansion of functions in the real domain
@Simon : as you understood, Iam not a cleaver user of MMa. The result you sent me is a perfect illustration of my problems (in a general manner). How can I simplify such above expression using the rules such as ArcTan[a]+ArcTan[b]=..., Log[a]+Log[b]=... ? Thanks for helping the old dinosaure !
