 Author Comment/Response Carbaboran 01/25/12 06:53am An easy way to solve this problem is to replace variables {x,y,..} by {x*epsilon, y*epsilon, ..} and make the expansion in epsilon. Afterwards set epsilon -> 1. Example: temp = Sqrt[1 - x^2 + y] temp = temp /. {x -> xp*\[Epsilon], y -> yp*\[Epsilon]} ExpandAll[Normal[Series[temp, {\[Epsilon], 0, 2}]]] % //. {\[Epsilon] -> 1,xp->x,yp->y} URL: ,
