How do I evaluate, in Mathematica, limits like this:

"X+Y" when X is much bigger than Y, i.e., when Y/X->0. The unswer should be X+Y->X.

Regards.

Perhaps you could see how to use this:

In[1]:= x+y/.y->10.^-100x

Out[1]= 1. x

let z = x/y:

F[x_, y_] := x + y

Normal[Series[F[x, z x], {z, 0, 0}]]
